Phone is now a pure on-device recorder: no accounts, no servers, no
background uploads (INTERNET permission gone). File sync is the user's
own tooling; the library adopts externally added files.
Android:
- Delete provider package (Nextcloud, custom SHONAR, sync-folder,
registry, auth, TOFU/TLS), sync stack (SyncWorker/Drain/Slots,
MigrationRunner), provider/storage/folder UI, AI-via-server details.
- Home shows a fixed 'on this phone' library; details keep playback,
rename, file info. Settings lose Network/provider/HTTP-logging.
- Library root is the stored folder or Music/Recordings; import is
double-scan proof (mutex + unique filePath index, migration v3->v4
dedupes by path) with regression tests.
- Drop okhttp/work/security-crypto/media deps; delete their tests.
Repo: backend/, desktop/, worker/, deploy/, shared/, server scripts
and docs removed; README rewritten; CI keeps the android job only.
