The schema/config/bindings/registry/dispatcher module, useKeybind hooks,
recording dialog, reworked shortcuts settings page, help dialog, and the
localized action labels — re-based onto current main rather than merged
(the branch predates 440+ commits including the session-tabs shortcuts).
Review fixes applied on top of the original:
- close_session_tab (alt+w) joins the schema with labels in every locale;
it shipped on main after the PR's base and would otherwise silently die.
- switch_context_surface's special-case in conflict resolution is now a
declared prefixStyle config property instead of a magic id string.
- Duplicate handler registration warns in dev builds.
- The risky-browser-shortcut warning inspects every chord and covers
mod+q/d/h/j/o/u plus mod+shift+w/q.
- The dispatcher remembers which target armed a two-chord prefix so the
window-level completion handler can distinguish a deliberate sequence
from typing in an editable field (guard lands with the dispatch hook).
- Schema tests: unique normalized default bindings enforced, and the
flat-file-era override format proven to keep resolving.
