Wire up new purgatory sync loop, remove legacy sync_state_git_data

Phase 13 of purgatory-sync-redesign:
- Add sync loop startup in main.rs (RealSyncContext + ThrottleManager + start_sync_loop)
- Update add_state() and add_pr() to automatically enqueue for background sync
- Remove start_state_sync() call from state.rs (now handled by sync loop)
- Remove orphaned legacy functions: sync_state_git_data, fetch_missing_oids_from_server,
  get_most_complete_local_repo, identify_missing_oids, get_date_of_most_recent_commit_on_default_branch
- Clean up unused imports in purgatory/mod.rs
