feat: fix task failures via sandbox improvements and display commits in Web UI

- Fix ephemeral sandbox deletion issue by passing $CLAUDOMATOR_PROJECT_DIR to agents and using it for subtask project_dir.
- Implement sandbox autocommit in teardown to prevent task failures from uncommitted work.
- Track git commits created during executions and persist them in the DB.
- Display git commits and changestats badges in the Web UI execution history.
- Add badge counts to Web UI tabs for Interrupted, Ready, and Running states.
- Improve scripts/next-task to handle QUEUED tasks and configurable DB path.
