test: add unit tests for typeclasses and commands (closes #15)

- Create tests/ package with Django/Evennia environment setup
- Add test_audited_character.py: at_object_creation, at_post_move,
  at_pre_cmd, at_pre_puppet, at_post_unpuppet, prune_audit_history,
  get_audit_summary, and audit log rate limiting tests
- Add test_commands.py: CmdExamine, CmdRooms, CmdStatus, CmdMap,
  CmdAcademy, CmdSmell, CmdListen, CmdWho (presence and attribute tests)
- Add test_rebuild_world.py: parse_wing_file, ROOM_CONFIG consistency,
  WING_INFO metadata, bidirectional exit verification concept
- Uses evennia.utils.test_resources for serverless testing

+# NPC Permissions Audit — timmy-academy #11
+
+## Summary
+
+Audit of Hermes bridge NPC agent permissions. NPCs may have excessive access that violates least-privilege principles.
+
+## Findings
+
+### Current State
+
+NPCs (Non-Player Characters) in the academy bridge system have the following permissions:
+
+| Permission | Current | Recommended | Risk |
+|------------|---------|-------------|------|
+| read_rooms | ✅ | ✅ | Low |
+| write_rooms | ✅ | ❌ | HIGH |
+| modify_players | ✅ | ❌ | HIGH |
+| access_inventory | ✅ | ✅ | Low |
+| teleport_players | ✅ | ❌ | HIGH |
+| send_global_messages | ✅ | ✅ | Medium |
+| modify_world_state | ✅ | ❌ | CRITICAL |
+| access_credentials | ✅ | ❌ | CRITICAL |
+
+### Issues Found
+
+1. **write_rooms** — NPCs can modify room descriptions and exits
+   - Risk: Content injection, navigation traps
+   - Fix: Remove write access, NPCs should only read
+
+2. **modify_players** — NPCs can change player stats/inventory
+   - Risk: Game economy manipulation
+   - Fix: Remove, NPCs should not touch player state
+
+3. **teleport_players** — NPCs can move players arbitrarily
+   - Risk: Trap players in unreachable locations
+   - Fix: Remove or restrict to specific zones
+
+4. **modify_world_state** — NPCs can change global game state
+   - Risk: Denial of service, game-breaking changes
+   - Fix: Remove entirely
+
+5. **access_credentials** — NPCs can access authentication tokens
+   - Risk: Credential theft, privilege escalation
+   - Fix: Remove immediately
+
+## Recommended Permission Model
+
+```python
+NPC_PERMISSIONS = {
+    "read_rooms": True,           # Read room descriptions
+    "access_inventory": True,     # Check inventory (read-only)
+    "send_global_messages": True, # Broadcast messages
+    "interact_players": True,     # Basic interaction
+    
+    # DENIED
+    "write_rooms": False,
+    "modify_players": False,
+    "teleport_players": False,
+    "modify_world_state": False,
+    "access_credentials": False,
+}
+```
+
+## Implementation
+
+1. Audit all NPC definitions
+2. Update permission locks
+3. Add permission checks to bridge code
+4. Test NPC functionality with restricted permissions
