refactor(webui): queue install and bundle tasks - v3.18

Web UI / logs:
- Strip ANSI escape codes and handle \r (progress bars) in task log output
- Add USB export API + UI card on Export page (list removable devices, write audit JSON or support bundle)
- Add Display Resolution card in Tools (xrandr-based, per-output mode selector)
- Dashboard: audit status banner with auto-reload when audit task completes

Boot & install:
- bee-web starts immediately with no dependencies (was blocked by audit + network)
- bee-audit.service redesigned: waits for bee-web healthz, sleeps 60s, enqueues audit via /api/audit/run (task system)
- bee-install: fix GRUB UEFI — grub-install exit code was silently ignored (|| true); add --no-nvram fallback; always copy EFI/BOOT/BOOTX64.EFI fallback path
- Add grub-efi-amd64, grub-pc, grub-efi-amd64-signed, shim-signed to package list (grub-install requires these, not just -bin variants)
- memtest hook: fix binary/boot/ not created before cp; handle both Debian (no extension) and upstream (x64.efi) naming
- bee-openbox-session: increase healthz wait from 30s to 120s

KVM console stability:
- runCmdJob: syscall.Setpriority(PRIO_PROCESS, pid, 10) on all stress subprocesses
- lightdm.service.d: Nice=-5 so X server preempts stress processes

Packages: add btop

+# Charting architecture
+
+## Decision: one chart engine for all live metrics
+
+**Engine:** `github.com/go-analyze/charts` (pure Go, no CGO, SVG output)
+**Theme:** `grafana` (dark background, coloured lines)
+
+All live metrics charts in the web UI are server-side SVG images served by Go
+and polled by the browser every 2 seconds via `<img src="...?t=now">`.
+There is no client-side canvas or JS chart library.
+
+### Why go-analyze/charts
+
+- Pure Go, no CGO — builds cleanly inside the live-build container
+- SVG output — crisp at any display resolution, full-width without pixelation
+- Grafana theme matches the dark web UI colour scheme
+- Active fork of the archived wcharczuk/go-chart
+
+### SAT stress-test charts
+
+The `drawGPUChartSVG` function in `platform/gpu_metrics.go` is a separate
+self-contained SVG renderer used **only** for completed SAT run reports
+(HTML export, burn-in summaries). It is not used for live metrics.
+
+### Live metrics chart endpoints
+
+| Path | Content |
+|------|---------|
+| `GET /api/metrics/chart/server.svg` | CPU temp, CPU load %, mem load %, power W, fan RPMs |
+| `GET /api/metrics/chart/gpu/{idx}.svg` | GPU temp °C, load %, mem %, power W |
+
+Charts are 1400 × 280 px SVG. The page renders them at `width: 100%` in a
+single-column layout so they always fill the viewport width.
+
+### Ring buffers
+
+Each metric is stored in a 120-sample ring buffer (2 minutes of history at 1 Hz).
+Buffers are per-server or per-GPU and grow dynamically as new GPUs appear.

+- `build-in-container.sh` targets `linux/amd64` builder containers by default, including Docker Desktop on macOS / Apple Silicon.

 **Critical invariants:**
 - `DEBIAN_KERNEL_ABI` in `iso/builder/VERSIONS` pins the exact kernel ABI used in BOTH places:
-  1. `setup-builder.sh` / `build-in-container.sh` / `build-nvidia-module.sh` — Debian kernel headers for module build
+  1. `build-in-container.sh` / `build-nvidia-module.sh` — Debian kernel headers for module build
   2. `auto/config` — `linux-image-${DEBIAN_KERNEL_ABI}` in the ISO
 - NVIDIA modules go to staged `usr/local/lib/nvidia/` — NOT to `/lib/modules/<kver>/extra/`.
+- `bee-gpu-burn` worker must be built against cached CUDA userspace headers from `build-cublas.sh`, not against random host-installed CUDA headers.
+- The live ISO must ship `libcublas`, `libcublasLt`, and `libcudart` together with `libcuda` so tensor-core stress works without internet or package installs at boot.
 - The source overlay in `iso/overlay/` is treated as immutable source. Build-time files are injected only into the staged overlay.
 - The live-build workdir under `dist/` is disposable; source files under `iso/builder/` stay clean.
 - Container build requires `--privileged` because `live-build` uses mounts/chroots/loop devices during ISO assembly.
+- On macOS / Docker Desktop, the builder still must run as `linux/amd64` so the shipped ISO binaries remain `amd64`.
+- Operators must provision enough RAM to hold the full compressed live medium plus normal runtime overhead, because `toram` copies the entire read-only ISO payload into memory before the system reaches steady state.

+# Decision: Treat memtest as explicit ISO content, not as trusted live-build magic
+
+**Date:** 2026-04-01
+**Status:** active
+
+## Context
+
+We have already iterated on `memtest` multiple times and kept cycling between the same ideas.
+The commit history shows several distinct attempts:
+
+- `f91bce8` — fixed Bookworm memtest file names to `memtest86+x64.bin` / `memtest86+x64.efi`
+- `5857805` — added a binary hook to copy memtest files from the build tree into the ISO root
+- `f96b149` — added fallback extraction from the cached `.deb` when `chroot/boot/` stayed empty
+- `d43a9ae` — removed the custom hook and switched back to live-build built-in memtest integration
+- `60cb8f8` — restored explicit memtest menu entries and added ISO validation
+- `3dbc218` / `3869788` — added archived build logs and better memtest diagnostics
+
+Current evidence from the archived `easy-bee-nvidia-v3.14-amd64` logs dated 2026-04-01:
+
+- `lb binary_memtest` does run and installs `memtest86+`
+- but the final ISO still does **not** contain `boot/memtest86+x64.bin`
+- the final ISO also does **not** contain memtest menu entries in `boot/grub/grub.cfg` or `isolinux/live.cfg`
+
+So the assumption "live-build built-in memtest integration is enough on this stack" is currently false for this project until proven otherwise by a real built ISO.
+
+## Decision
+
+For `bee`, memtest must be treated as an explicit ISO artifact with explicit post-build validation.
+
+Project rules from now on:
+
+- Do **not** trust `--memtest memtest86+` by itself.
+- A memtest implementation is considered valid only if the produced ISO actually contains:
+  - `boot/memtest86+x64.bin`
+  - `boot/memtest86+x64.efi`
+  - a GRUB menu entry
+  - an isolinux menu entry
+- If live-build built-in integration does not produce those artifacts, use an explicit project-owned mechanism such as:
+  - a binary hook copying files into `binary/boot/`
+  - extraction from the cached `memtest86+` `.deb`
+  - another deterministic build-time copy step
+- Do **not** remove such explicit logic later unless a fresh real ISO build proves that built-in integration alone produces all required files and menu entries.
+
+Current implementation direction:
+
+- keep the live-build memtest stage enabled if it helps package acquisition
+- but enforce memtest explicitly in a project-owned binary hook
+- patch the generated `binary/boot/grub/grub.cfg` and `binary/isolinux/live.cfg` directly in the binary stage if memtest entries are missing
+
+## Consequences
+
+- Future memtest changes must begin by reading this ADR and the commits listed above.
+- We should stop re-introducing "prefer built-in live-build memtest" as a default assumption without new evidence.
+- Memtest validation in `build.sh` is not optional; it is the acceptance gate that prevents another silent regression.
+- If we change memtest strategy again, we must update this ADR with the exact build evidence that justified the change.

+# ISO Build Rules
+
+## Verify package names before use
+
+ISO builds take 30–60 minutes. A wrong package name wastes an entire build cycle.
+
+**Rule: before adding any Debian package name to the ISO config, verify it exists and check its file list.**
+
+Use one of:
+- `https://packages.debian.org/bookworm/<package-name>` — existence + description
+- `https://packages.debian.org/bookworm/amd64/<package-name>/filelist` — exact files installed
+- `apt-cache show <package>` inside a Debian bookworm container
+
+This applies to:
+- `iso/builder/config/package-lists/*.list.chroot`
+- Any package referenced in bootloader configs, hooks, or overlay scripts
+
+## Memtest rule
+
+Do not assume live-build's built-in memtest integration is sufficient for `bee`.
+We already tried that path and regressed again on 2026-04-01: `lb binary_memtest`
+ran, but the final ISO still lacked memtest binaries and menu entries.
+
+For this project, memtest is accepted only when the produced ISO actually
+contains all of the following:
+
+- `boot/memtest86+x64.bin`
+- `boot/memtest86+x64.efi`
+- a memtest entry in `boot/grub/grub.cfg`
+- a memtest entry in `isolinux/live.cfg`
+
+Rules:
+
+- Keep explicit post-build memtest validation in `build.sh`.
+- If built-in integration does not produce the artifacts above, use a
+  deterministic project-owned copy/extract step instead of hoping live-build
+  will "start working".
+- Do not switch back to built-in-only memtest without fresh build evidence from
+  a real ISO.
+- If you reference memtest files manually, verify the exact package file list
+  first for the target Debian release.

+# Validate vs Burn: Hardware Impact Policy
+
+## Validate Tests (non-destructive)
+
+Tests on the **Validate** page are purely diagnostic. They:
+
+- **Do not write to disks** — no data is written to storage devices; SMART counters (power-on hours, load cycle count, reallocated sectors) are not incremented.
+- **Do not run sustained high load** — commands complete quickly (seconds to minutes) and do not push hardware to thermal or electrical limits.
+- **Do not increment hardware wear counters** — GPU memory ECC counters, NVMe wear leveling counters, and similar endurance metrics are unaffected.
+- **Are safe to run repeatedly** — on new, production-bound, or already-deployed hardware without concern for reducing lifespan.
+
+### What Validate tests actually do
+
+| Test | What it runs |
+|---|---|
+| NVIDIA GPU | `nvidia-smi`, `dcgmi diag` (levels 1–4 read-only diagnostics) |
+| Memory | `memtester` on a limited allocation; reads/writes to RAM only |
+| Storage | `smartctl -a`, `nvme smart-log` — reads SMART data only |
+| CPU | `stress-ng` for a bounded duration; CPU-only, no I/O |
+| AMD GPU | `rocm-smi --showallinfo`, `dmidecode` — read-only queries |
+
+## Burn Tests (hardware wear)
+
+Tests on the **Burn** page run hardware at maximum or near-maximum load for extended durations. They:
+
+- **Wear storage**: write-intensive patterns can reduce SSD endurance (P/E cycles).
+- **Stress GPU memory**: extended ECC stress tests may surface latent defects but also exercise memory cells.
+- **Accelerate thermal cycling**: repeated heat/cool cycles degrade solder joints and capacitors over time.
+- **May increment wear counters**: GPU power-on hours, NVMe media wear indicator, and similar metrics will advance.
+
+### Rule
+
+> Run **Validate** freely on any server, at any time, before or after deployment.
+> Run **Burn** only when explicitly required (e.g., initial acceptance after repair, or per customer SLA).
+> Document when and why Burn tests were run.

+# ISO Build
+
+`bee` ISO is built inside a Debian 12 builder container via `iso/builder/build-in-container.sh`.
+
+## Requirements
+
+- Docker Desktop or another Docker-compatible container runtime
+- Privileged containers enabled
+- Enough free disk space for builder cache, Debian live-build artifacts, NVIDIA driver cache, and CUDA userspace packages
+
+## Build On macOS
+
+From the repository root:
+
+```sh
+sh iso/builder/build-in-container.sh
+```
+
+The script defaults to `linux/amd64` builder containers, so it works on:
+
+- Intel Mac
+- Apple Silicon (`M1` / `M2` / `M3` / `M4`) via Docker Desktop's Linux VM
+
+You do not need to pass `--platform` manually for normal ISO builds.
+
+## Useful Options
+
+Build with explicit SSH keys baked into the ISO:
+
+```sh
+sh iso/builder/build-in-container.sh --authorized-keys ~/.ssh/id_ed25519.pub
+```
+
+Rebuild the builder image:
+
+```sh
+sh iso/builder/build-in-container.sh --rebuild-image
+```
+
+Use a custom cache directory:
+
+```sh
+sh iso/builder/build-in-container.sh --cache-dir /path/to/cache
+```
+
+## Notes
+
+- The builder image is automatically rebuilt if the local tag exists for the wrong architecture.
+- The live ISO boots with Debian `live-boot` `toram`, so the read-only medium is copied into RAM during boot and the runtime no longer depends on the original USB/BMC virtual media staying present.
+- Target systems need enough RAM for the full compressed live medium plus normal runtime overhead, or boot may fail before reaching the TUI.
+- The NVIDIA variant installs DCGM 4 packages matched to the CUDA user-mode driver major version. For driver branch `590` / CUDA `13.x`, the package family is `datacenter-gpu-manager-4-cuda13` rather than legacy `datacenter-gpu-manager`.
+- Override the container platform only if you know why:
+
+```sh
+BEE_BUILDER_PLATFORM=linux/amd64 sh iso/builder/build-in-container.sh
+```
+
+- The shipped ISO is still `amd64`.
+- Output ISO artifacts are written under `dist/`.
