Michael Chus d1a22d782d Move power diag tests to validate/stress; fix GPU burn power saturation

- bee-gpu-stress.c: remove per-wave cuCtxSynchronize barrier in both
  cuBLASLt and PTX hot loops; sync at most once/sec so the GPU queue
  stays continuously full — eliminates the CPU↔GPU ping-pong that
  prevented reaching full TDP
- sat_fan_stress.go: default SizeMB 0 (auto = 95% VRAM) instead of
  hardcoded 64 MB; tiny matrices caused <0.1 ms kernels where CPU
  re-queue overhead dominated
- pages.go: move nvidia-targeted-power and nvidia-pulse from Burn →
  Validate stress section alongside nvidia-targeted-stress; these are
  DCGM pass/fail diagnostics, not sustained burn loads; remove the
  Power Delivery / Power Budget card from Burn entirely

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 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 iso/builder/build-in-container.sh --authorized-keys ~/.ssh/id_ed25519.pub

Rebuild the builder image:

sh iso/builder/build-in-container.sh --rebuild-image

Use a custom cache directory:

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:

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/.
