type: changed
area: overlay

- Added configurable overlay shortcuts for session help, controller select, and controller debug actions.
- Added mpv/plugin and CLI routing for session help, controller utilities, and subtitle sidebar toggling through the shared session-action path.
- Improved dedicated overlay modal retry and focus handling for runtime options, Jimaku, session help, controller tools, and the playlist browser.
- Fixed controller configuration and controller debug shortcut opens so configured bindings bring up their modals again instead of tripping renderer recovery.
