opencrabs 0.3.54

//! Detail popup overlay — opens on Enter, dismissed on Esc.
//!
//! Renders the full record for the currently-selected item in the
//! focused panel. Inbox proposals show their rationale + tool/command
//! definition; activity entries show the parsed metadata; schedule
//! rows show the cron expression + paused/next-run state.
//!
//! Pure read of `app.mc` snapshots — no service calls during render.
