Eric Garcia 174eb40da9 feat: RFC 0049 synchronous guard command - implemented
Guard now runs synchronously before tokio runtime initialization:
- Added maybe_handle_guard_sync() pre-main check
- Added run_guard_sync() with full guard logic
- Added is_in_allowlist_sync() and is_source_code_path_sync()
- main() now checks for guard before calling tokio_main()

This eliminates tokio overhead for guard invocations and provides
correct architecture (pre-init gates don't depend on post-init infra).

Note: PATH-based command lookup still hangs in Claude Code's hook
environment - this is a Claude Code issue, not Blue. The hook still
requires full binary path as workaround.
