fix(ci): remove repo-name-dependent test assertions and stale tracked file

- Fix @archon/paths test that expected 'remote-coding-agent' in path
  (fails on Archon repo checkout). Now checks path exists instead.
- Fix @archon/cli tests that matched 'remote-coding-agent' directory name.
- Remove .agents/examples/codex-telegram-bot/package-lock.json that
  snuck past .gitignore.
