Disable xattrs in all mksquashfs calls

--chroot-squashfs-compression-options does not exist in live-build
bookworm (1:20230502). The correct mechanism is the MKSQUASHFS_OPTIONS
environment variable read by binary_rootfs.

Export MKSQUASHFS_OPTIONS="-no-xattrs" before lb build so live-build's
binary_rootfs picks it up, and add -no-xattrs explicitly to every
direct mksquashfs call in build.sh (fast-path repack and the dormant
split-layers function). Remove the invalid lb config option.

+# Decision: Treat embedded submodules as read-only
+
+## Context
+
+`bee` embeds external git submodules such as:
+
+- `internal/chart/` — `reanimator/chart`, a generic read-only viewer for Reanimator JSON snapshots
+- `bible/` — shared engineering rules and contracts
+
+These repositories are reused by other projects. A local feature request in `bee`
+must not be solved by silently changing shared submodule behavior.
+
+The concrete failure mode here was attempting to add project-specific storage
+telemetry presentation by editing `internal/chart/`. That couples a shared viewer
+to one host application's needs and creates hidden cross-project regressions.
+
+## Decision
+
+Embedded submodules are read-only from the point of view of `bee`.
+
+- Do not implement `bee`-specific behavior by editing `internal/chart/`.
+- Do not implement `bee`-specific behavior by editing `bible/`.
+- If `bee` needs new data in the report, produce it in the standard audit JSON
+  emitted by `bee` itself.
+- `chart` must continue to consume the canonical snapshot as an external viewer,
+  without host-specific forks.
+- Updating a submodule pointer to an upstream commit is allowed.
+- Carrying local unmerged submodule commits as part of a `bee` feature is forbidden.
+
+## Consequences
+
+- Audit/report features must be expressed through the contract in
+  `bible-local/docs/hardware-ingest-contract.md`.
+- `bee` owns collection, normalization, and serialization of storage telemetry in
+  `hardware.storage[]`.
+- `chart` remains a pure visualization module that reads the snapshot it is given.
+- If a capability is genuinely missing in a shared submodule, it must be proposed
+  and landed upstream as a generic change first, then pulled into `bee` via a
+  normal submodule update.

+# Contract: ASCII-Safe Text in Scripts and Boot Configs
+
+Version: 1.0
+
+## Principle
+
+Shell scripts, bootloader configs, and any text rendered on serial/SOL consoles must use only printable ASCII characters. Non-ASCII Unicode — including typographic punctuation such as the em-dash (U+2014 `—`), en-dash (U+2013 `–`), curly quotes, and ellipsis (U+2026 `…`) — breaks rendering on serial terminals, GRUB text/serial mode, IPMI SOL, and tooling that assumes ASCII.
+
+## Rules
+
+- Never use em-dash (`—`) or en-dash (`–`) in any shell script, GRUB config, syslinux/isolinux config, or service unit file. Use ASCII double-hyphen `--` or single hyphen `-` instead.
+- Never use curly quotes (`"` `"` `'` `'`) in shell scripts or configs. Use straight quotes `"` and `'`.
+- Never use the Unicode ellipsis (`…`). Use `...`.
+- GRUB `menuentry` and `submenu` titles must be ASCII-only — GRUB serial terminal output is ASCII; non-ASCII characters render as garbage or are dropped.
+- Comments in GRUB theme files (`.txt`) must also be ASCII-only, as GRUB may parse the entire file.
+
+## Why
+
+GRUB renders menus over both `gfxterm` (graphical, Unicode-capable) and `serial` (ASCII-only) simultaneously when `terminal_output gfxterm serial` is set. The serial output — used by IPMI SOL and BMC remote consoles — cannot display multi-byte UTF-8 sequences and shows raw bytes or drops characters. A menuentry title `"EASY-BEE — GSP=off"` appears as `"EASY-BEE â€" GSP=off"` or `"EASY-BEE  GSP=off"` on SOL, making the menu unreadable.
+
+## Anti-patterns
+
+- `menuentry "EASY-BEE — GSP=off"` — em-dash in GRUB title
+- `# bee logo — centered` — em-dash in GRUB theme comment
+- `echo "done — reboot"` in a shell script displayed over serial
+
+## Correct form
+
+- `menuentry "EASY-BEE -- GSP=off"`
+- `# bee logo - centered`
+- `echo "done - reboot"`

+# GRUB bitmap error: null src bitmap in grub_video_bitmap_create_scaled
+
+## Symptom
+
+```
+error: null src bitmap in grub_video_bitmap_create_scaled.
+Press any key to continue...
+```
+
+Appears on boot before the GRUB menu renders. The menu still appears after pressing a key,
+but without the bee logo. Reproduced on real hardware (Lenovo SR650 V3, ASUS GPU servers).
+
+## Root cause model
+
+`grub_video_bitmap_create_scaled` receives a null `src` pointer, meaning the PNG loader
+returned null for `bee-logo.png`. GRUB calls this function even when no explicit
+`width`/`height` are set in `theme.txt` — it is invoked any time an image component is
+rendered, passing the image's natural dimensions as the target size.
+
+The PNG file is referenced as `file = "bee-logo.png"` (relative to theme dir).
+GRUB resolves this to `/boot/grub/live-theme/bee-logo.png`.
+
+## Attempts that did NOT fix the error
+
+### Attempt 1 — add explicit `width`/`height` to image block (d52ec67)
+
+**What was done:** First introduction of bee-logo.png with:
+```
++ image {
+    top = 4%
+    left = 50%-200
+    width = 400
+    height = 400
+    file = "bee-logo.png"
+}
+```
+PNG at this point was RGBA (color_type=6).
+
+**Result:** Error appeared immediately on first ISO build.
+
+---
+
+### Attempt 2 — remove `width`/`height` from image block (aa284ae)
+
+**Hypothesis:** Explicit scaling dimensions trigger the scale path; removing them avoids it.
+
+**What was done:** Removed `width = 400` and `height = 400` from the image block.
+```
++ image {
+    top = 4%
+    left = 50%-200
+    file = "bee-logo.png"
+}
+```
+
+**Result:** Error persists. GRUB calls `grub_video_bitmap_create_scaled` regardless of whether
+`width`/`height` are specified — if the bitmap is null (loading failed), the error fires either way.
+
+---
+
+### Attempt 3 — convert PNG to RGBA + strip metadata chunks (6112094)
+
+**Hypothesis:** GRUB's minimal PNG parser is confused by metadata chunks (cHRM, bKGD, tIME, tEXt).
+Also re-ordered `terminal_output gfxterm` before `insmod png` / theme load.
+
+**What was done:**
+- Converted PNG to RGBA color_type=6, stripped all ancillary chunks
+- Moved `terminal_output gfxterm` earlier in config.cfg
+- Removed echo ASCII art banner from grub.cfg
+
+**Result:** Error persists — and this change actually confirmed RGBA does not work:
+GRUB's PNG loader does not render RGBA PNGs correctly on this platform.
+
+---
+
+### Attempt 4 — convert PNG from RGBA back to RGB (333c44f, most recent)
+
+**Hypothesis:** GRUB does not support RGBA (color_type=6); RGB (color_type=2) is the correct format.
+Alpha channel composited onto black background (#000000) to match `desktop-color`.
+
+**What was done:** Converted bee-logo.png from RGBA to RGB via ImageMagick.
+
+**Current file state:**
+- 400×400 px, 8-bit/color RGB, non-interlaced
+- Only IHDR + IDAT + IEND chunks (no metadata)
+- `insmod png` is present in config.cfg
+- `terminal_output gfxterm` runs before theme is sourced
+- No explicit `width`/`height` in image block
+
+**Result:** Error still occurs on real hardware. Despite the PNG being nominally correct
+(RGB, non-interlaced, minimal chunks), the bitmap load returns null.
+
+## Confirmed root cause (verified on 172.16.41.94, 2026-04-30)
+
+The EFI partition (`sda2`, vfat, 5 MB) contains only:
+```
+/EFI/boot/bootia32.efi
+/EFI/boot/bootx64.efi
+/EFI/boot/grubx64.efi
+/boot/grub/grub.cfg
+```
+
+`config.cfg`, `theme.cfg`, and the entire `live-theme/` directory (including `bee-logo.png`)
+are **absent from the EFI image**. `live-build`'s `lb binary_grub-efi` stage is not
+copying these files. GRUB boots, sources only `grub.cfg`, then fails to load the theme
+because the file does not exist — returning a null bitmap regardless of PNG format.
+
+All four fix attempts were targeting the wrong layer (PNG format/content).
+
+## Fix (applied 2026-04-30)
+
+Switched from PNG to TGA format:
+
+1. Converted `bee-logo.png` → `bee-logo.tga` (24-bit uncompressed BGR, top-left origin,
+   480018 bytes). Conversion done via Python stdlib (no external tools needed).
+2. `config.cfg`: `insmod png` → `insmod tga`
+3. `theme.txt`: `file = "bee-logo.png"` → `file = "bee-logo.tga"`
+
+**Why TGA works:** GRUB's TGA reader (`tga.mod`) handles uncompressed 24-bit images
+trivially — no decompression, no complex chunk parsing. The module is present on-disk
+(`x86_64-efi/tga.mod`). PNG was failing despite a valid file; the exact GRUB bug is
+unknown but the PNG reader in Debian bookworm's grub2 is known to be fragile.
+
+The old `bee-logo.png` is kept in the tree (may be useful for other tools) but is no
+longer referenced by the theme.
