Fix CI: Update scripts for robustness and timeouts

- Updated `scripts/ci/run-ios-simulator.sh`:
  - Replaced `simctl bootstatus` with a manual polling loop to support older simctl versions and avoid "illegal option" errors.
  - Logging is directed to stderr.
- Updated `scripts/ci/start-android-emulator.sh`:
  - Explicitly create the log directory before redirection.
  - Fixed `pgrep` usage to avoid script failure if no process is found.
  - Improved `sdkmanager` invocation robustness against broken pipes.
  - Added timeout logic to boot wait loop.
- Updated `.github/workflows/maven.yml`:
  - Added `timeout-minutes` to Android (20m) and iOS (20m) jobs to prevent long hangs.
