- Replace TextContent = None with proper fallback class in all MCP tool modules
- Fixes TypeError when MCP library is not fully initialized in test environment
- Ensures all 700 tests pass (was 699 passing, 1 failing)
- Affected files:
* packaging_tools.py
* config_tools.py
* scraping_tools.py
* source_tools.py
* splitting_tools.py
The fallback class maintains the same interface as mcp.types.TextContent,
allowing tests to run successfully even when the MCP library import fails.
Test results: ✅ 700 passed, 157 skipped, 2 warnings
