[loop-cycle-30] fix: gitea-mcp binary name + test stabilization

1. gitea-mcp → gitea-mcp-server (brew binary name). Fixes Timmy's
   Gitea triage — MCP server can now be found on PATH.
2. Mark test_returns_dict_with_expected_keys as @pytest.mark.slow —
   it runs pytest recursively and always exceeds the 30s timeout.
3. Fix ruff F841 lint in test_cli.py (unused result= variable).
