feat(mcp): add CLI transport options and simplify CLAUDE.md (#209)

Add CLI argument parsing for MCP server with --transport, --host, and --port
options supporting stdio, SSE, and HTTP transports. Simplify CLAUDE.md from
646 to 83 lines by consolidating content into a compact quick-reference format
with tables and links to detailed documentation.

Changes:
- Add argparse CLI handling in __main__.py for transport configuration
- Update main() signature with explicit transport, host, port parameters
- Update server tests to match new function signature
- Fix test import issues by adding mock_paginated_response_factory fixture
  to avoid conftest.py namespace conflicts across packages
