refactor(test): consolidate FakeApp and add sys.modules isolation utility
- Extract tests/utils/import_isolation.py with isolated_sys_modules context manager - Extend tests/factories/app.py FakeApp with handler-specific attributes - Refactor test_chat_handler.py to use centralized FakeApp and cached imports - Refactor test_command_handler.py with mock_execute_factory fixture - Refactor test_smoke.py to move import-time sys.modules manipulation into fixture - Add SQLite migration integration tests (G-002) - Add HTTP API smoke integration tests (G-005) - Update CI workflow to call pytest for SQLite migrations (G-004) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Unit tests for CommandHandler behavior patterns.
|

Unit tests for CommandHandler - REAL imports.
|

|

Tests cover command processing patterns:
|
||||
- Command parsing and routing
|
||||
- Event emission pattern
|
||||
- Command manager interaction
|
||||
- Privilege handling
|
||||
|
||||
Uses pattern-based testing to avoid circular import issues in source code.
|
||||
Tests the actual CommandHandler class from production code.
|
||||
Uses tests.utils.import_isolation to break circular import chain safely.
