Two related bugs were producing different map keys for identical
hardware depending on whether the inventory probe ran in the reporter
on the Proxmox host or in the live-image agent after PXE boot.
1. diskSerial read /sys/block/<dev>/device/{serial,vpd_pg80} and only
TrimSpace'd the result. vpd_pg80 is a binary SCSI VPD page with a
4-byte header, and some SSDs leak NUL/control bytes into the text
serial file. Those bytes survive into the Go string, lowercase
unchanged, and become a garbage map key that the reporter's cleaner
read can't match. Sanitize to ASCII-printable range at ingest.
2. probeGPUs built the model slug from fields[2] + " " + fields[3] of
`lspci -mm -nnk` output. fields[3] is subsystem vendor/device info,
which varies between otherwise-identical cards and carries the
`-rXX` revision marker — stable-enough for display but not for
identity. Use fields[2] alone, strip the trailing `[NNNN]` PCI
device-ID that lspci -nn appends, and sanitize for consistency.
After deploying the new orchestrator + re-running the configure step
on each registered host, SpecValidate will match cleanly. Disk diffs
self-resolve because the reporter already stored clean serials; GPU
diffs need one reporter re-run because the old expected slug still
carries subsystem noise.
