Clean up Unity and Python tests (CoplayDev#548)

* Test suite audit: remove placeholders, consolidate duplicates, fix stale tests

Python tests:
- Delete 3 vestigial placeholder files (test_script_editing.py, test_find_in_file_minimal.py, test_resources_api.py)
- Remove empty skip-marked tests from test_transport_framing.py and test_logging_stdout.py
- Consolidate DummyMCP/setup_tools() into test_helpers.py
- Fix flaky timing in test_telemetry_queue_worker.py (200ms → 500ms)
- Remove placeholder from test_instance_routing_comprehensive.py

C# tests:
- Consolidate MCPToolParameterTests.cs (755 → 361 lines, -52%)
- Fix 3 tests with stale "future feature" comments - features ARE implemented:
  - AutoGrow arrays (Phase 1.2)
  - Path normalization (Phase 1.1)
  - Bulk array mapping (Phase 3.1)
- Strengthen assertions in ManageGameObjectTests.cs and CommandRegistryTests.cs

* Address code review feedback: remove dead code, fix silent test skips

- Remove unused tools_struct setup in test_edit_normalization_and_noop.py
- Create test texture in EndToEnd_PropertyHandling_AllScenarios so
  texture-dependent scenarios (4, 5, 10) actually run instead of silently skipping
- Add texture cleanup in finally block
