"""Replay all 72 golden fixtures against the Python research_md port.

Two independent lifecycle runs matching the two capture scripts:
1. capture-fixtures.mjs — the "happy path" lifecycle
2. capture-edge-cases.mjs — edge cases, errors, boundary conditions

Each run gets a fresh temp dir with its own project state.
