The new react-hooks lint rule "Calling setState synchronously within an
effect can trigger cascading renders" flagged real anti-patterns in
four spots. Refactored each per the rule's intent (derive during render,
or use useSyncExternalStore for external subscriptions).
1. hooks/useMediaQuery.ts — replaced the useState + useEffect pair with
useSyncExternalStore. That's the canonical React hook for
subscribing to external stores (matchMedia in this case) without
mirroring into local state via an effect. Snapshot/getServerSnapshot
pair preserves the SSR-safe behaviour.
2. components/network/nodes/DeviceNode.tsx — the prop-sync useEffect
that copied nodeData.label into labelValue was redundant.
labelValue is the EDIT BUFFER; while not editing, the displayed
span now reads nodeData.label directly. The buffer is initialized
only when an edit session starts (onDoubleClick).
3. components/network/nodes/GroupNode.tsx — same pattern, same fix.
4. components/dashboard/TicketQueue.tsx — the
setTickets([]) + setLoading(true) + fetchTickets() chain in the
effect was the cascade. Pushed those writes inside fetchTickets
(after the function boundary, so they batch with the eventual
setTickets(result)). Added a request-id ref so a slow first
response can't overwrite a fast second one.
Frontend lint: 20 errors → 0 errors. tsc -b clean.

- WhatWeKnow shows a "synthesizing" indicator + skeleton pulse while the
chat cycle is in-flight; task-lane header mirrors the signal with a
"thinking" pip so engineers know the AI is still working.
- Quiet-state hint when the lane is open (facts exist) but no open
questions, checks, or active fix — keeps the surface from looking
"finished" when the AI is about to follow up.
- Keyboard shortcuts: ⌘↵/Ctrl+↵ send in the composer (plain Enter still
sends), ⌘G toggles the Script Generator panel for the active fix,
`?` opens a new ShortcutsHelpOverlay listing all bindings. ⌘K palette
was already wired in TopBar.
- Responsive: below 1200px the task lane collapses to a bottom drawer
with a backdrop + a floating "Tasks ●" toggle button. TaskLane now
takes a `variant: 'side' | 'drawer'` prop; drawer variant drops the
resize handle and uses the shared slide-in-bottom animation.
- Build hygiene: fixed a pre-existing TS error in confirm-post error
handling (duplicate `response` type keys) and an unused-import warning
in TemplatizePrompt.
Verified: `npx tsc -b` and `npm run build` both clean against the dev
stack; Vite HMR applied each change without errors.
