mollify-parse

Python parsing for Mollify. Parser abstraction so the rest of the engine never touches the concrete parser directly.

ADR-0001: full-fidelity ruff AST

Built on Astral's ruff_python_parser / ruff_python_ast (pinned git rev) — the same battle-tested, error-resilient parser that powers ruff. The types below (ParsedModule, Definition, Import, …) are parser-agnostic, so the concrete parser remains an implementation detail confined to this crate.
