aristo-cli 0.1.0

//! `aristo canon refresh` — invalidate the canon-match cache and
//! re-run the match call against every annotation in the index.
//!
//! Equivalent to `aristo stamp --refresh-canon`, but doesn't re-run
//! the stamp pipeline itself (no source walk, no body-hash drift
//! check, no index rewrite). Useful when:
//!
//! - The user knows the catalog has a new version they want to pull
//!   matches against, but doesn't need a fresh stamp.
//! - A `Degraded` outcome in a prior stamp left the cache partial;
//!   refresh re-tries the API call without other work.
//!
//! Same client-selection precedence as the runner; same graceful-
//! degradation handling for unreachable / unauth'd / 5xx responses.
