deep profile + threshold gating + firmware stage + Burn super-stage

Ships all five phases of the deep-profile overhaul together. Runs now
carry a profile (quick/deep/soak); every profile walks the same
11-stage order — Inventory → Firmware → SpecValidate → SMART →
CPUStress → Storage → Network → Burn → GPU → PSU → Reporting —
with only per-stage durations and concurrency scaled.

Phase 1: profiles.ProfileRegistry loaded from vetting.yaml; runs.profile
column + CreateWithProfile; threshold table + evaluator seeded per-run
from the shared vetting.thresholds block; breach flips result at
/sensor + /result.

Phase 2: upgraded CPUStress (stress-ng --cpu-method=all --verify +
EDAC/MCE poll), Storage (fio --verify=md5 + SMART start/end delta),
Network (sustained iperf + /proc/net/dev deltas) with per-profile
knobs from Deps.

Phase 3: Burn super-stage with goroutine fan-out for CPU + memory +
fio + iperf, PSU rails sampled across the Burn window, SensorMux
(2 s flush, 500-sample cap) to absorb backpressure.

Phase 4: Firmware stage + firmware_snapshots table; probes dmidecode
(BIOS), ipmitool (BMC), ethtool -i (NIC), nvme (sysfs + id-ctrl),
lspci (HBA), /proc/cpuinfo (microcode). spec.DiffFirmware folds into
SpecValidate with pin-by-identifier and fan-out-across-component
matching; mismatches park the run in FailedHolding.

Phase 5: profile radio on the host start form, profile chip on the
run header, Firmware section in the HTML report, coverage artifact
uploaded from CI, agent/tests/fakes/ scaffold with Deps.LookPath
seam + stress_ng and dmidecode example fakes.
