codewhale-tui 0.9.5

//! Legacy executable plugin-tool inventory (`[tools].plugin_dir`).
//!
//! These are scripts, not declarative bundles: they are discovered by
//! scanning a directory, they carry their own approval requirement, and
//! they never share bundle trust state. `/plugin tools` reports them
//! read-only — nothing here installs, trusts, or executes anything.
