feat(ios): launch fixes, SideStore CI, and AltStore source

Runtime:
- Fix main.dart/router.dart import cycle and GoRouter redirect blocking
- Use app support storage on iOS (Android-only external storage)
- Safe connectivity checks, update API timeouts, mobile init guards
- Remote debug logging for future mobile diagnostics

CI (upstream-compatible):
- Restore full multi-platform debugbuild workflow
- SideStore IPA packaging in MACOSIOS
- AltStore source generation in DEPLOY (docs/altstore-source.json)
- Drop fork-only OTA GitHub Pages flow

+# Remote debug logging
+
+Floaty can mirror app logs and uncaught Flutter/Dart errors to an external HTTP
+endpoint for debugging white-screen or startup issues.
+
+Remote logging is off by default. Enable it at build or run time with Dart
+defines:
+
+```sh
+flutter run -d linux \
+  --dart-define=FLOATY_REMOTE_LOG_ENDPOINT=https://example.com/floaty-logs
+```
+
+If the endpoint requires bearer auth, also pass:
+
+```sh
+--dart-define=FLOATY_REMOTE_LOG_TOKEN=your-token
+```
+
+The app sends JSON payloads with a session id, timestamp, platform, level, and
+message. The developer logs screen can also upload the currently selected app or
+download log view on demand.
+
+Before logs are saved or sent, common authorization, token, and cookie patterns
+are redacted.
