fix: Add defensive imports for MCP package in install_skill tests

- Added try/except around 'from mcp.types import TextContent' in test files
- Added @pytest.mark.skipif decorator to all test classes
- Tests now gracefully skip if MCP package is not installed
- Fixes ModuleNotFoundError during test collection in CI

This follows the same pattern used in test_mcp_server.py (lines 21-31).

All tests pass locally: 23 passed, 1 skipped
