A crash mid-command (e.g. the nvbandwidth reboot) previously lost that
job's entire output: streamExecOutput only buffered stdout/stderr in
memory and the job's log file was written once, after the process
exited. It now also streams each line straight to that file as it
arrives, so whatever printed before a crash survives.
Root filesystem here is a tmpfs overlay (toram boot), so the only real
persistence boundary is blackbox's mirror to removable media, not the
local write itself. platform.SetJobBoundaryHook lets app wire a touch
of a small kick-file after each job's output is written; blackboxWorker
now polls that file's mtime alongside its normal adaptive timer and
syncs immediately on a kick instead of waiting out the current flush
period (up to 30s).
An agent handed a bundle path had no way to know its layout without
grepping through random logs first — confirmed by watching a separate
session read bee-nvidia.log before anything else on a real bundle. Embeds
a single README.md (bee-embed, internal/app/assets/) explaining what bee
is and giving direct answers to the questions someone analyzing a bundle
is most likely to ask (did the tests pass, what hardware is this, is a
service healthy, RAID/GPU/NVLink state, etc), written at the bundle root
by both BuildSupportBundle (support-bundle archive root, sibling of
manifest.txt) and blackboxWorker.syncCycle (removable-media boot-folder
root, which otherwise has no manifest.txt-equivalent pointing anywhere).

- sat.go: DetectGPUVendor lspci fallback now checks GPU device classes
([0300]/[0302]/[0380]) per line instead of scanning the whole output for
vendor name; AMD EPYC servers have dozens of AMD-branded PCIe entries
(Root Complex, IOMMU, Host Bridge) that were triggering the old check
- blackbox.go: fix deadlock in finishCycle — it held w.mu while calling
persistState(), which acquires rt.mu then re-acquires w.mu inside
persistStateLocked(); now w.mu is released before persistState()
- build.sh: remove NVIDIA-specific overlay files (bee-gpu-burn,
bee-john-gpu-stress, bee-nccl-gpu-stress, bee-nvidia-recover,
bee-dcgmproftester-staggered, bee-check-nvswitch,
nvidia-fabricmanager.service.d/) for non-nvidia build variants
- bee-selfheal: gate NVIDIA recovery on BEE_GPU_VENDOR=nvidia so the
script does not attempt to restart bee-nvidia.service on NOGPU builds
