brokk-bifrost-python 0.9.2

//! The Python answers behind `PythonAdapter`.
//!
//! `LanguageAdapter` is analysis-owned, so the trait impl itself stays in
//! `analyzer/python/adapter.rs`; every answer it gives comes from here or from
//! [`crate::declarations`]. `synthesize_hydrated_units` is the one exception:
//! it mutates `FileState`, an analysis type, and stays with the shell.
