//! `confium search [<interface>] [<algorithm>]`.
//!
//! Fetches the registry master index and, for each entry, the per-plugin
//! version index + latest manifest. Filters by the requested interface
//! and/or algorithm. Prints a table of matches.
//!
//! Filtering is case-insensitive on the interface name (so `AEAD` and
//! `aead` match). Algorithm filtering is case-sensitive (algorithm names
//! are canonical: `SHA-256`, `AES-256-GCM`).
