SomnoTrace v4.0.0-beta1

The SomnoBridge release. 🌉 SomnoTrace now pairs, provisions, time-syncs
and pulls therapy data through the Wi-Fi↔BLE bridge — the AirSense's SD
card never has to leave the machine.

✨ Highlights

• 🌉 SomnoBridge integration — a complete BLE client (sb_ble,
  ~1.5k LoC): discovery, passkey pairing, bonded GATT ops over the
  framed protocol, streaming file pulls, and a /api/sb/op HTTP proxy
  that drives every bridge op from the portal.
• 🕐 Authoritative UTC & drift correction — SomnoTrace anchors its
  NTP time on the bridge's monotonic clock with periodic exchanges,
  reads back the fitted drift on every sync pass, and applies the
  estimate when importing sessions — AS11 clock wander is corrected
  instead of silently skewing therapy data.
• ⚙️ "Configure SomnoBridge" dialog — card network picker (scrollable
  AP list, OPEN/SECURED badges, saved network), AS10/AS11 machine cards
  with the AS11 GMT-offset picker, an X close button, and an
  insecure-card flow: factory 88888888 and open cards are detected by
  a real probe-join, flagged with a warning, and can be re-secured
  in-place via EZSHARE_ADMIN — the bridge changes the card's own Wi-Fi
  password through its admin form and rejoins automatically.
• 📊 Bridge status in the portal — pairing state, card Wi-Fi,
  therapy-active and transfer-allowed indicators, last sync, and sync
  progress straight from the bridge.
• 📥 Session augmentation — late-recovered stream files now merge
  into already-committed sessions instead of being discarded as
  duplicates; coverage is verified against the manifest and annotations
  are regenerated byte-identically.

🐛 Fixes

• 🗂️ Duplicate recording folders — oximetry day labels are now a pure
  function of the recording's civil digits (ESP-local noon rule) and an
  existing recording_id under any day folder wins — DST/offset changes
  can no longer file one recording under two days.
• 🔁 Uploader fingerprint ping-pong — duplicate recording_ids across
  day folders are deduplicated in reconcile (newest day wins) so two
  files can never take turns invalidating each other's uploads.
• 🛑 Retry storms — any unit that fails 5 uploads is parked and
  retried at most once a day, reviving automatically when its content
  changes. A local anomaly can never again become hours of HTTP 429s.
• 📱 Logs tab scroll — narrow screens no longer open the log view at
  the oldest line of a page-long scrollback.

🏗️ Under the hood

• sb_proto request/response framing with reassembly; BLE ops run off
  the NimBLE host task so provisioning never starves indications.
• Transfer ledger coordination keeps already-downloaded card files from
  re-pulling — zero redundant transfers across reconnects.
• edf_import events rendering extracted behind a byte-identical
  emit-to-file / emit-to-set abstraction for coverage checks.
• AS11 BLE: connection handling improvements alongside the bridge path.

✅ Testing

• New sb_ble_test host suite: 153 checks covering pairing state
  machine, framing, reassembly and op dispatch.
• somno_ml_worker survivor tests: guards, deadlines, SST checks,
  fragment grouping.
• Full host suite: 31 targets, 0 failures, sanitizer-clean.
