docs: add comprehensive parameter documentation to all API methods (#86)
Enhanced documentation for the mcrfpy module with: - Detailed docstrings for all API methods - Type hints in documentation (name: type format) - Return type specifications - Exception documentation where applicable - Usage examples for complex methods - Module-level documentation with overview and example code Specific improvements: - Audio API: Added parameter types and return values - Scene API: Documented transition types and error conditions - Timer API: Clarified handler signature and runtime parameter - UI Search: Added wildcard pattern examples for findAll() - Metrics API: Documented all dictionary keys returned Also fixed method signatures: - Changed METH_VARARGS to METH_NOARGS for parameterless methods - Ensures proper Python calling conventions Test coverage included - all documentation is accessible via Python's __doc__ attributes and shows correctly formatted information. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
