Harden MCP tool parameter handling to eliminate “invalid param” errors (#339)
* feat: migrate to FastMCP 2.0 (v2.12.5)
- Update pyproject.toml to use fastmcp>=2.12.5 instead of mcp[cli]
- Replace all imports from mcp.server.fastmcp to fastmcp
- Maintain MCP protocol compliance with mcp>=1.16.0
- All 15 files updated with new import statements
- Server and tools registration working with FastMCP 2.0
* chore: bump MCP for Unity to 6.2.2 and widen numeric tool params (asset search/read_resource/run_tests) for better LLM compatibility
* chore: bump installed server_version.txt to 6.2.2 so Unity installer logs correct version
* fix(parameters): apply parameter hardening to read_console, manage_editor, and manage_gameobject
- read_console: accept int|str for count parameter with coercion
- manage_editor: accept bool|str for wait_for_completion with coercion
- manage_gameobject: accept bool|str for all boolean parameters with coercion
- All tools now handle string parameters gracefully and convert to proper types internally
* chore(deps): drop fastmcp, use mcp>=1.18.0; update imports to mcp.server.fastmcp
* chore(deps): re-add fastmcp>=2.12.5, relax mcp to >=1.16.0
Adds fastmcp as explicit dependency for FastMCP 2.0 migration.
Relaxes mcp version constraint to support broader compatibility.

* test: remove obsolete mcp stubs for FastMCP 2.0 compatibility
Removes stub mcp modules from test files that were conflicting with
the real mcp and fastmcp packages now installed as dependencies.
Adds tests/__init__.py to make tests a proper Python package.
This fixes test collection errors after migrating to FastMCP 2.0.
Test results: 40 passed, 7 xpassed, 5 skipped, 1 failed (pre-existing)

* fix: complete FastMCP 2.0 migration with correct import paths
Updates all remaining files to use `from fastmcp import` instead of
the old `from mcp.server.fastmcp import` path.
Changes:
- server.py: Update FastMCP import
- tools/__init__.py: Update FastMCP import
- resources/__init__.py: Update FastMCP import
- tools/manage_script.py, read_console.py, resource_tools.py: Update imports
