fix(ci): add emulator to PATH and increase CUA smoke timeout to 60min (#27)

* fix(ci): add emulator to PATH and increase CUA smoke timeout to 60min

- Add 'Add emulator to PATH' step after setup-android so emulator binary
  is found (was: command not found, causing adb wait-for-device to hang
  until the 30min job timeout)
- Increase timeout-minutes from 30 to 60 to accommodate full build
- Add npm cache and Gradle cache (same as build.yml) to speed up rebuild

* fix: address code review findings for cua-emulator-path

- Fix stale Gradle cache causing build failure after package rename
  (ai.opencode.mobile → cc.agentlabs.opencode): add purge step matching
  the one already present in publish-play-store.yml
- Fix adb launch command using old package name ai.opencode.mobile;
  updated to cc.agentlabs.opencode/.MainActivity
