* Fix #478: Add Matrix4x4Converter to prevent Cinemachine serialization crash

The `get_components` action crashes Unity when serializing Cinemachine
camera components because Newtonsoft.Json accesses computed Matrix4x4
properties (lossyScale, rotation) that call ValidTRS() on non-TRS matrices.

This fix adds a safe Matrix4x4Converter that only accesses raw matrix
elements (m00-m33), avoiding the dangerous computed properties entirely.

Changes:
- Add Matrix4x4Converter to UnityTypeConverters.cs
- Register converter in GameObjectSerializer serializer settings

Tested with Cinemachine 3.1.5 on Unity 6 - get_components now returns
full component data without crashing.

* Add unit tests for Matrix4x4Converter

Tests cover:
- Identity matrix serialization/deserialization
- Translation matrix round-trip
- Degenerate matrix (determinant=0) - key regression test
- Non-TRS matrix (projection) - validates ValidTRS() is never called
- Null handling
- Ensures dangerous properties are not in output

* Address code review feedback

- Fix null handling consistency: return zero matrix instead of identity
  (consistent with missing field defaults of 0f)
- Improve degenerate matrix test to verify:
  - JSON only contains raw mXY properties
  - Values roundtrip correctly
- Rename test to reflect expanded coverage

* Move tests to TestProject per review feedback

Moved Matrix4x4ConverterTests from MCPForUnity/Editor/Tests/ to
TestProjects/UnityMCPTests/Assets/Tests/EditMode/Helpers/ as requested.

Also added MCPForUnity.Runtime reference to the test asmdef since
the converter lives in the Runtime assembly.

* Fix test teardown to avoid dropping MCP bridge

CodexConfigHelperTests was calling MCPServiceLocator.Reset() in TearDown, which disposes the active bridge/transport during MCP-driven test runs. Replace with restoring only the mutated service (IPlatformService).

* Avoid leaking PlatformService in CodexConfigHelperTests

Capture the original IPlatformService before this fixture runs and restore it in TearDown. This preserves the MCP connection safety fix (no MCPServiceLocator.Reset()) while avoiding global state leakage to subsequent tests.
