chore(release): v1.4.0

Shortcuts gain several bindings per action, mouse buttons and a searchable
picker, and the stored shortcut schema changes shape, so this is a minor bump.
Existing shortcuts migrate on first launch.

Play release notes state that this release carries no mobile feature changes;
the work is desktop-only.

+
+### Added
+- **Several shortcuts per action.** Every action now holds a list of bindings
+  instead of a single one, so a second (or third) shortcut can be added with the
+  `+` button and removed individually.
+- **Mouse buttons as shortcuts.** Side buttons (back / forward) can be bound on
+  their own; right and middle click require a modifier. Left click cannot be
+  bound because it drives every on-screen interaction. Mouse events cannot be
+  swallowed, so a bound button still performs its original action — the settings
+  screen says so before the binding is saved.
+- **Pick a key from a searchable list.** Besides pressing the key, a shortcut can
+  now be chosen from a grouped dropdown with a search box inside it, which also
+  makes keys reachable that are awkward to press while recording.
+- **The history and command popups are rebindable.** `Ctrl+Shift+V` and
+  `Ctrl+Shift+C` were fixed in code and had no settings entry; they are now
+  ordinary actions. The voice command shortcut, which had never been exposed in
+  settings, is visible as well.
+
+### Fixed
+- **Double-press hands-free never triggered.** Dictation and hands-free ship with
+  the same default key and are told apart by the double press, but shortcut
+  lookup stopped at the first match, so hands-free was unreachable in installed
+  builds. Both actions now receive the event and are split by press type.
+- **Reserved system shortcuts could be assigned anyway.** The check compared
+  joined key names, so pressing the modifiers in a different order let `Ctrl+C`
+  and friends through. Combinations are now compared structurally.
+- **Turning shortcuts off also killed the popup shortcuts permanently.** Disabling
+  global shortcuts released every registration in the process, including ones it
+  did not own, and re-enabling never restored them.
+- **Enabling shortcuts after starting with them off left nothing bound.**
+- **Shortcut labels were frozen in the language they were recorded in** and did not
+  follow the app language or platform conventions. They are now derived on display.
+- **The dashboard caption indicator never reflected the real state** because the
+  event payload was stored instead of the state inside it.
+
+### Changed
+- Shortcuts are stored as one list per action. Existing shortcuts are migrated
+  automatically on first launch; no reconfiguration is needed.
