sessionwiki 0.13.0

//! Golden-file tests for the session adapters.
//!
//! These guard the most fragile part of the project: parsing three different
//! JSONL/JSON schemas that drift between tool versions. Each fixture under
//! `tests/fixtures/<tool>/` is a small, realistic session including the edge
//! cases the parsers are supposed to handle (boilerplate dropping, subagent
//! detection, malformed lines, multi-block content, skipped roles).
//!
//! When a tool changes its format, a fixture from the new version plus an
//! assertion here is the cleanest possible bug report and regression test.
