- Restore MCP server configurations in .mcp.json with updated paths
for separate virtual environments (core/.venv and tools/.venv)
- Align Python version: change .python-version from 3.13 to 3.11
to match pyproject.toml target version
- Remove AGENTS.md as suggested (quickstart is sufficient)
- Document cross-package imports and separate venv architecture
in ENVIRONMENT_SETUP.md
