queelius/jsonl-algebra: v1.04.1: CLAUDE.md accuracy rewrite

Changes Documentation Complete CLAUDE.md rewrite based on spec-vs-implementation audit (15 corrections) Fixed critical "streaming by default" misrepresentation — core operations use List[Row], streaming available via Pipeline(lazy=True) Fixed incorrect Pipeline.run() API example (actual API is __call__()) Corrected subcommand count (18 top-level, 23 leaf commands) Added missing aggregation functions (first, last), full shell command list, window function syntax Documented security boundary (export csv --apply) and select expression limitations Code Removed dead --flatten flag from project CLI subparser (parsed but never used by handle_project()) Tests All 299 tests passing
