v3.2.5

Sleep stages on Aerivue — SomnoStage hypnograms now upload to Aerivue
in SomnoTrace's native SST1 binary format, in addition to the existing
CSV uploads to SMB:
- 📦 Uploaded as-is — the original epoch grid is preserved (30 s for
  AirSense 11 and full-rate rings, 32 s for Gen1 O2 Rings at 0.25 Hz) with
  per-epoch confidence scores intact. No conversion, no resampling, no
  Zeo grid.
- 🔀 Per-backend format routing — each upload destination now declares
  which stage format it consumes (SMB → CSV, Aerivue → SST), with separate
  CSV and SST fingerprints in upload state. A rescore that changes the
  .sst re-uploads to Aerivue without disturbing SMB's CSV state — and a
  CSV-only change never re-triggers an SST upload.
- 🔍 Direct SST discovery — valid .sst sidecars are found directly
  under streams/ and oximetry/recordings/ too, so a hypnogram still
  uploads even when its CSV export doesn't exist (e.g. freshly-rescored
  files). PARTIAL (still-growing) and INSUFFICIENT (not enough valid
  oximetry) sidecars are never uploaded.
- 📤 Each backend's refused/accepted stage files are logged from the
  server's import response, and a refused stage file fails the day so it
  retries instead of being silently marked done.
- 🧩 Backend capacity raised 4 → 8 and BreathingRoom is pre-declared as an
  SST consumer — adding the next stage endpoint is now a flag flip, not a
  framework rework.

SMB "Test Connection" false failure (fixes #330) — after the first
successful upload the test wrongly reported "write test failed" forever:
its DATALOG probe hit STATUS_OBJECT_NAME_COLLISION ("directory already
exists"), which vendored libsmb2 never surfaces via smb2_get_nterror().
The firmware now recovers the real status from libsmb2's error string —
no vendored-library patch needed. The same fix also repairs adaptive
SMB-signing retry when a subfolder path is configured (Windows 11 24H2+
servers that require signing were falsely reported as "folder not found").

📄 New spec: 0015-somnostage-sst-format.md — the complete SST1 byte
layout, stage/confidence encoding, flag semantics and epoch-grid rules,
written for third-party endpoints implementing .sst ingestion.
🧪 Expanded host tests: dual-format tracking, format-isolated fingerprint
invalidation, SST header/size/flag validation, 32 s Gen1 grids, SST-only
discovery, and reboot persistence.
