SomnoTrace v3.2.3

✨ New Features

• 😴 Sleep stage export (SomnoStage) — hypnograms are now exported as
  Zeo-compatible CSV files to .somnotrace/stages/ on the SD card and uploaded
  automatically alongside CPAP and oximetry data. SMB uploads land in
  SOMNOSTAGE/<YYYYMM>/ and exports are back-filled automatically for
  recordings that predate this release.
• 🖼️ Brand logos on the portal — the SleepHQ, Aerivue, and BreathingRoom
  upload cards now show real logos loaded from each service's site, with a
  graceful fallback to the built-in icon if the image can't be fetched.

🚀 Improvements

• 📁 Tidier SMB folders — oximetry and stage uploads are now grouped into
  one folder per month (OXIMETRY/<YYYYMM>, SOMNOSTAGE/<YYYYMM>) instead of
  one folder per day. Existing folders are left untouched.
• 📊 Consistent progress display — the portal now shows upload progress in
  days for all three streams (CPAP · Oximetry · Stages), matching the
  "days to keep in sync" setting. A day counts as done only when every
  recording in it is uploaded.
• ⚡ Faster upload passes — the SD card is scanned once per pass and shared
  across all enabled backends, instead of being re-scanned (and every file
  re-checksummed) once per backend.
• 🧠 Smarter memory use — upload buffers were right-sized (~4× smaller per
  recording), the per-pass recording cap grew from 128 to 768, and a failed
  allocation now degrades gracefully instead of aborting the whole pass.

🐛 Fixes

• 🔄 Reset Upload State now resets everything (#317) — oximetry and stage
  upload history is cleared along with CPAP, so all three streams re-upload
  after a reset instead of only CPAP.
• ⏱️ Uploader no longer stalls or spins — fixed timing edge cases and
  therapy-hold handling that could starve the watchdog or burn CPU while
  uploads were deferred.
• 🏷️ No more stale update badge — the "update available" badge no longer
  resurrects a cached version tag after an OTA flash; it stays quiet until the
  first live check.
• ✏️ OXYMETRY → OXIMETRY — fixed the long-standing typo in storage paths
  and all upload backends (your NAS folder is now spelled correctly).
• 💤 "SleepHQ Cloud" → "SleepHQ" — simplified the backend label and portal
  card title.
