judgment 0.10.1

Added

• jud --replay DIR RUBRIC, or JUD_REPLAY=DIR, answers from the recordings
  under a directory through the crate's Replay backend instead of a server:
  no key, no network, a state nobody recorded is an error. The README's
  command-line transcript runs this way over examples/recordings/ and
  tests/jud_cli.rs holds it to what the binary prints.
• docs/stability.md: what is promised across versions. jud/v1 is stable, a
  minor version only adds, readers accept every v1 document for at least
  twelve months after a later minor is published, fingerprints exclude the
  envelope and never change for a document's spec; the crate's 0.x rule and
  the command's contract.
• Decision 0020, proposed and not applied: whether a v1 minor stays in the
  apiVersion string or moves to a minor field under apiVersion: jud/v1,
  each option priced.
• scripts/record_demo.sh (mise run demo) records the command-line demo as
  an asciinema cast, docs/demo.cast, from the recordings, with no network;
  regenerated by the release bump so the version it shows is the release's.
• mise run ci is an alias of mise run check, the gates in CI order.

Changed

• The README opens with the command line for 0.10: a one-line pitch, the mise
  install, the cat event.json | jud triage.jud transcript with the verdicts
  the binary prints for examples/jud/triage.jud, then the Rust API; one
  comparison table of the four properties where the clients differ, the full
  grids linked; the live example's capture trimmed to the command and its
  output.
