StillHammer 9105610b29 feat: Add integration tests 8-10 & fix CTest configuration
Added three new integration test scenarios:
- Test 08: Config Hot-Reload (dynamic configuration updates)
- Test 09: Module Dependencies (dependency injection & cascade reload)
- Test 10: Multi-Version Coexistence (canary deployment & progressive migration)

Fixes:
- Fixed CTest working directory for all tests (add WORKING_DIRECTORY)
- Fixed module paths to use relative paths (./ prefix)
- Fixed IModule.h comments for clarity

New test modules:
- ConfigurableModule (for config reload testing)
- BaseModule, DependentModule, IndependentModule (for dependency testing)
- GameLogicModuleV1/V2/V3 (for multi-version testing)

Test coverage now includes 10 comprehensive integration scenarios covering
hot-reload, chaos testing, stress testing, race conditions, memory leaks,
error recovery, limits, config reload, dependencies, and multi-versioning.

/**
* @file test_03_stress_test.cpp
* @brief Scenario 3: Stress Test - Long-duration stability validation
*
* OBJECTIVE:
* Validate hot-reload system stability over extended duration with repeated reloads.
*
* TEST PARAMETERS:
* - Duration: 10 minutes (36000 frames @ 60 FPS)
* - Reload frequency: Every 5 seconds (300 frames)
* - Total reloads: 120
* - No random crashes - focus on hot-reload stability
*
* SUCCESS CRITERIA:
* ✅ All 120 reloads succeed
* ✅ Memory growth < 50MB over 10 minutes
* ✅ Average reload time < 500ms
* ✅ FPS remains stable (no degradation)
* ✅ No file descriptor leaks
* ✅ State preserved across all reloads
*
* WHAT THIS VALIDATES:
* - No memory leaks in hot-reload system
* - No file descriptor leaks (dlopen/dlclose)
* - Reload performance doesn't degrade over time
* - State preservation is reliable at scale
* - System remains stable under repeated reload stress
