docs/parity/feature-matrix.md keeps the 401 Next UI row ids and adds a CLI and a TUI column (pass, todo, partial, n/a with reasons), computed by scripts/parity-matrix.py from the copied Next matrix (docs/parity/next-feature-matrix.md) and the status table in the script. First fill of the CLI column after the M1 work so far. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
