Desktop global hotkey default CmdOrCtrl+Shift+G collides with app shortcuts (Illustrator ungroup, Finder Go to Folder) — ship globalHotkey unbound like Talk, add hotkey overrides UI

The macOS desktop client registers a GLOBAL shortcut on CmdOrCtrl+Shift+G by default (GLOBAL_SHORTCUT_DEFAULTS.globalHotkey). A global registration outranks every app's own shortcuts, so in Adobe Illustrator, Shift+Cmd+G (ungroup — a core, constant-use command) silently does nothing and yanks focus to the Vellum client instead (invisible steal: no window raised). Cmd+Shift+G is also Finder 'Go to Folder'. Reproduced and root-caused Sep 20, 2026; verified in the client's own log ([global-shortcuts] registered globalHotkey: CmdOrCtrl+Shift+G). The user's only fix today is hand-editing the electron-store config.json (hotkeys.globalHotkey: "") and relaunching — no settings UI exists for hotkey overrides. Two asks: (1) ship the globalHotkey UNBOUND by default, exactly as the Talk chord already is — the source comment on Talk states the principle perfectly: 'there is no chord we can pick that is not load-bearing somewhere'; Cmd+Shift+G is load-bearing in Illustrator. (2) expose hotkey overrides (settings.hotkeys) in the settings UI so users can rebind without editing JSON on disk.
