Implements the app side of M7 push (docs/android/PLAN.md §11). The app EMBEDS
its own distributor — ntfy is only the relay server, no second app installed,
no Google Play Services. New feature slice; no existing screen's data flow
changes.
- core/push: NtfyTopic (random unguessable topic + endpoint/SSE URL builders),
PushTickle (content-free { stream, ref } parser over ntfy's SSE envelope),
NtfyStreamClient (bare-client OkHttp SSE to <ntfy>/<topic>/sse, reconnect/
backoff cloned from ShardStreamClient), PushNotifier (channels + per-stream
deep-link notification), PushService (foreground service holding the
connection), PushManager (mint topic / register-unregister device / start-stop,
keyed to the session), PushPreferences (DataStore state).
- data: NotificationsApi + DTOs + NotificationsRepository over the merged
/auth/me/devices + /auth/me/notifications/* contract; push block on SettingsDto.
- ui/notifications: settings screen + VM — per-stream toggles, personal streams
greyed until a game account is linked, POST_NOTIFICATIONS request on enable.
- Navigation: Routes.NOTIFICATIONS + stream→route deep-link map, menu entry,
RunicApp + MainActivity intent handling; teardown wired into logout + server
switch (deregister while bearer valid) and every sign-out (local, via session
observer).
- Manifest: POST_NOTIFICATIONS + FOREGROUND_SERVICE(_DATA_SYNC) + the service.
Deviation (recorded in PLAN.md): direct-ntfy transport, no UnifiedPush library
— the plan's stated likely path; keeps the APK Google-free and dependency-light,
with a PushResult/transport seam for a future FCM Play flavor. Requires the small
companion push.ntfyUrl settings field (website#<pr>).
18 new JVM tests; :app:testDebugUnitTest + lintDebug + assembleDebug green.
