Module overlay 

Overlay subsystem: full-screen popups that take over the body+status area (file picker, help). App holds an Option<Box<dyn Overlay>>; events route through it first when present.

Modules

help

Help overlay: lists every binding from KEY_REGISTRY, grouped by category, with type-to-filter. User remaps from keys.toml replace the displayed keys per command_name.

picker

File picker overlay. Lists every file in the working set, supports type-to-filter, Enter to open, Ctrl-D to drop.

tag_picker

Tag picker overlay (:tselect). Lists every match for a tag name and lets the user pick one with the keyboard. Enter dispatches a SelectTagMatch(idx) command back to the app loop.

Structs

OverlayContext

Borrowed slice of app state that overlays need at refresh time. Kept narrow so the trait doesn’t pull in the whole app.
