InputActor

[Source]

Reads terminal input, parses events, routes to focused widget. Listens for SIGWINCH to detect terminal resize.

Focus is scope-aware: widgets are registered with an optional scope token. Disabling a scope removes its widgets from the active focus list. Widgets with no scope (None) are always active.
