feat(grasp-audit): add explicit purgatory tests

Add PurgatoryTests module with tests for GRASP-01 purgatory behavior:
- Announcement purgatory tests (tolerant of unimplemented feature)
- State event purgatory tests (already implemented)
- PR purgatory tests (tolerant of unimplemented feature)

Tests pass regardless of purgatory implementation status, enabling
development without breaking the test suite. When features are
implemented, tests will verify correct purgatory behavior.

+//! Purgatory Integration Tests
+//!
+//! Tests ngit-grasp relay's implementation of GRASP-01 purgatory behavior.
+//! Uses grasp-audit library to avoid code duplication.
+//!
+//! # Test Strategy
+//!
+//! - Each test runs in complete isolation with its own fresh relay instance
+//! - Uses macro to eliminate boilerplate while maintaining test isolation
+//! - Calls individual test methods from grasp-audit for minimal duplication
+//! - Automatic cleanup via TestRelay fixture (removes container and temp dirs)
+//!
+//! # Running Tests
+//!
+//! ```bash
+//! # Run all purgatory tests
+//! cargo test --test purgatory
+//!
+//! # Run specific test
+//! cargo test --test purgatory test_state_event_not_served_before_git_data
+//!
+//! # With output
+//! cargo test --test purgatory -- --nocapture
+//! ```
