Test MatchScene initialization and lifecycle - TEST-002 complete (26 tests)

Browse Source 
Add comprehensive test coverage for the main game scene:

Test Coverage:
- Constructor and scene key registration
- init() method - state reset
- create() method - board setup, StateRenderer creation, event subscription
- update() loop - intentionally minimal design
- shutdown() method - cleanup and event unsubscription
- Event handling - state updates and resize events
- Event subscription lifecycle - proper bind/unbind
- Integration tests - full lifecycle execution
- Edge cases - rapid cycles, large states

Key Testing Challenges Solved:
- Phaser canvas dependency - mocked Phaser.Scene with minimal API
- gameBridge integration - mocked event system with spy functions
- StateRenderer mocking - included all necessary methods (clear, getPlayerZones, etc.)
- Container API - added removeAll() for proper cleanup testing

All 1,282 tests passing (26 new MatchScene tests).

Foundation for TEST-004 (Card rendering) and TEST-005 (StateRenderer).
