pub const KNOWN_DEPS: &[&str];Expand description
Plugin-accessible dep names per docs/specs/plugin-api.md. The
header validator rejects any token outside this list; the
consumer maps these strings back to its own enum at registration
time. Exposed pub so consumer-side drift-detection tests can
iterate the same catalog rather than hard-coding a parallel list
(a third copy that could itself fall out of sync).
