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.

+//! GRASP-01 Purgatory Tests
+//!
+//! Tests for the GRASP-01 purgatory mechanism where events are accepted but not
+//! served until corresponding git data arrives.
+//!
+//! ## Purgatory Behavior (GRASP-01 Line 22)
+//!
+//! "New repository announcements, repo state announcements, PRs and PR Updates
+//! SHOULD be accepted with message 'purgatory: won't be served until git data arrives'
+//! and kept in purgatory (not served) until the related git data arrives and otherwise
+//! discarded after 30 minutes."
+//!
+//! ## Test Categories
+//!
+//! ### Announcement Purgatory (feature not yet implemented)
+//! - `test_announcement_not_served_before_git_data`
+//! - `test_announcement_served_after_git_push`
+//! - `test_bare_repo_exists_for_purgatory_announcement`

+//! ### State Event Purgatory (already implemented)
+//! - `test_state_event_not_served_before_git_data`

+//!
+//! ### PR Purgatory (already implemented)
