* feat(search): add global command palette with cross-node stacks
Press Ctrl+K from anywhere to open a search palette that jumps to
pages, switches nodes, or opens stacks on any online node in the
fleet. Trigger lives as an icon in the top bar. Replaces the former
sidebar-scoped Ctrl+K handler.
The cross-node stack search fan-out is extracted into a shared hook
so the sidebar and palette stay in sync on the same debounce +
abort shape.
* fix(search): drop render-time ref write and effect-based query reset
Replace `nodesRef.current = nodes` during render with direct use of
`nodes` in the stack select callback, and fold the query-reset logic
into a single `onOpenChange` handler so it no longer runs via an
effect. Both changes resolve react-hooks rule violations that broke
frontend lint in CI.
* chore: ignore .superpowers/ brainstorm scratch dir
* feat(sidebar): add useStackMenuItems hook with grouped menu model
Pure transform hook that converts StackMenuCtx into four ordered MenuGroup
arrays (inspect, organize, lifecycle, destructive). Shared type contract in
sidebar-types.ts gives both the ContextMenu and DropdownMenu a single source
of truth so they cannot drift. Covered by 8 unit tests.
* refactor(sidebar): stabilize useStackMenuItems memoization deps
Destructure menuVisibility flags into primitive deps so inline object
literals from callers do not defeat memoization. Add a test confirming
isBusy disables all lifecycle items.
* feat(sidebar): add usePinnedStacks hook with per-node localStorage
* refactor(sidebar): stabilize usePinnedStacks eviction signal and isPinned dep
Change evictedOldest shape to { file, seq } so consumer effects re-fire on
repeated evictions. Narrow isPinned's useCallback dep to the current node's
pinned list so it only rebinds on local changes. Add test for eviction
side-effect and a second test for the seq counter.
* feat(sidebar): add useSidebarGroupCollapse hook with per-node keys
* refactor(sidebar): tighten useSidebarGroupCollapse effect ordering
Collapse the two write/read effects into a single skip-next-write ref
pattern so switching nodes no longer writes the previous node's map under
the new key before hydration. Also skip the no-op mount write. Add test
for setCollapsed.
* feat(sidebar): add row + group-header style helpers
* feat(sidebar): add SidebarBrand with mono kicker + serif hero
* feat(sidebar): add SidebarActions wrapper for create + scan
* feat(sidebar): extract SidebarSearch with kbd pill
* feat(sidebar): add StackRow with cyan-rail active state
* refactor(sidebar): dedupe tooltip markup in StackRow, widen test coverage
Extract a local RowTooltip helper so the update and git-pending branches
share the CursorProvider scaffolding. Add four behavioral tests covering
click, keyboard activation, kebab stop-propagation, and the busy loader
branch.
* feat(sidebar): unify context + kebab menus via useStackMenuItems
* feat(sidebar): add StackGroup with collapse and pinned variant
* feat(sidebar): add StackList with pinned + label groups
* feat(sidebar): add SidebarActivityTicker with idle fallback
* feat(sidebar): add StackSidebar container composing the regions
* feat(sidebar): replace sidebar block with StackSidebar composition
* docs(sidebar): add stack sidebar feature page with screenshots
* fix(sidebar): satisfy react-hooks purity and memoization rules
* fix(sidebar): restore "Sencho Logo" alt text for E2E selector
