feat(nexus): extend command palette search + fix shortcut destructure

CommandPalette now consumes CommandPaletteContext (open/setOpen) and
the internal Cmd+K useEffect is gone — the provider owns the global
listener. The search index gains live groups for conversations (via
chatApi.listConversations) and studio workshops (mapped from the
phase 10 WorkshopSlugs), plus stubbed entries for 8 settings section
anchors that will resolve once phase 13 splits InstanceGeneralSettings
into cards. Recipes are stubbed as a disabled placeholder pending
v1.8's recipe API.

useKeyboardShortcuts: adds `onSearch` to the destructure (the phase
6/11 review noted it was referenced at line 25 but never destructured
at lines 12-17) and adds it to the useEffect dependency list.
