fix(mcp-ansible): use local source install instead of uvx

The mcp-ansible package is not published to PyPI, causing uvx to fail.
Changed entrypoint to run directly from local source installation:
- Uses `uv pip install -e .` for local editable install
- Entrypoint: `python src/ansible_mcp/server.py`
- MCP handshake validated: ansible-mcp v1.26.0

Status: WORKING (29/38 MCP servers production ready)
