Stacked on #JS-9863 search-channels branch (targets it so only this feature shows in the diff).

What

• 
  Global OS shortcut (default Cmd/Ctrl+Shift+Space, rebindable in the shortcut editor) and a tray → Search item open a Spotlight-style quick search panel — a small frameless always-on-top window — even when the app is minimized or hidden in the tray.


• 
  Quick search panel: hosts only the global search popup. Esc/click-away dismisses, repeat hotkey toggles, stays warm for instant re-open. Picking a result fronts the main window and opens it there.


• 
  Spaceless boot: the panel skips WorkspaceOpen, per-space subscriptions, chat globals and the per-space subSpace fan-out — it runs only profile + spaceview subscriptions (lite createGlobal) plus the pin gate, in parallel. isCurrentSpace() now requires a non-empty space so the cross-space loader is used.


• 
  Onboarding: on first search open, a full-view state inside the search screen — real results fading into "Meet the new search", kind chips, and the live key combo. Any keypress dissolves it into the search.


• 
  Conflict handling: failed OS registration (combo taken) surfaces as a warning on the shortcut editor row; Wayland shows "not available"; web mode is unaffected.

Notes

• Design spec: docs/superpowers/specs/2026-08-25-global-search-shortcut-design.md
  


• Dev conveniences: panel auto-opens detached DevTools and never blur-hides in development builds.


• Manual test matrix (OS-global hotkeys aren't automatable): macOS minimized/hidden/tray, Windows focus-steal path, Linux X11; combo conflict (e.g. 1Password holding the default).
