refactor: remove separate process, delete test-app, simplify diagnostics

- Remove CheckRunnerService and :checks process — the ECONNREFUSED
  issue was caused by Android per-app network restriction, not Vector
  runtime. Checks run directly in the main process now.
- Delete test-app entirely — all diagnostics are now in the VPN Hide app
- Remove test-app from CI, lint, .gitignore, and update-version.sh
- Add lsposed/native to version update script and CI lint
