[codex] add Wear OS quick capture

[colonelpanic8]

Summary

Adds a native Wear OS companion app for Mova quick todo capture.

The watch app can capture a todo with the default org-agenda-api template, stores failed submissions locally, and retries queued items. The Android phone app syncs active Mova server credentials to Wear OS through the Wear Data Layer whenever credentials are saved, loaded, updated, or cleared.

Validation

• yarn typecheck

• yarn lint

• yarn test:unit --runInBand --no-watchman

• nix develop --impure .#android --command bash -lc 'cd android && ./gradlew :wear:assembleDebug :app:compileDebugKotlin'

• nix develop --impure .#android --command bash -lc 'cd android && ./gradlew :wear:lintDebug'

• nix develop --impure .#android --command bash -lc '$ANDROID_HOME/build-tools/36.0.0/aapt dump badging android/wear/build/outputs/apk/debug/wear-debug.apk | rg "watch|launchable|uses-feature|wearable|application-label|sdkVersion|package:"'

Notes

• Runtime testing on a physical Wear OS device/emulator is still pending.
• The feature intentionally propagates server credentials onto the Wear device so it can capture directly without the phone app in the foreground.
