fix(dashboard): real-time recipe-run feedback + clear run→inbox output trail

[kungfuk3nnyyy]

Summary

• Problem 1 — Stale runs after triggering: handleRunConfirm now calls refetchRuns() and refetchRecipes() immediately after a successful run POST, matching the pattern handleToggle already used for refetchRecipes.
• Problem 2 — In-progress runs don't progress: Runs poll interval is now adaptive. A useEffect watches the runs list for in-flight statuses (running/queued/pending) and sets runsIntervalMs to 3 000 ms while any are in-flight, back to 10 000 ms when idle. A prevInFlightRef gates setRunsIntervalMs so it only fires on actual transitions — no render loop.
• Problem 3 — Status pill lag: layout.tsx recipes intervalMs reduced from 30 000 → 10 000 ms so the pill reconciles within ~10 s after a run or toggle.
• Inbox legibility: The "Latest inbox output" card is relabelled "Latest output → Inbox" with "delivered N ago" copy and a "View in inbox →" link. Each row in the "Recent runs" list that carried inboxOutputs now shows a subtle → inbox link to the delivered item. A useEffect with lastSeenCompletedSeqRef fires a "Output delivered to inbox" toast (with "View in inbox" action) exactly once per newly-completed run that produced output — it skips existing runs on initial load.

Render-loop guarantee

runsIntervalMs is updated only when in-flight presence changes, not on every render. prevInFlightRef stores the previous boolean and the setRunsIntervalMs call is guarded by if (prevInFlightRef.current === hasInFlight) return.

Test plan

• Trigger a run → verify "Recent runs" and summary update within 3 s (not 10 s)
• While a run is running, verify the poll interval drops to ~3 s (observable via Network tab)
• After a run that delivers inbox output, verify a single "Output delivered to inbox" toast appears with a working "View in inbox" link
• Reload the page — confirm no toast fires for existing completed runs on initial load
• Verify run rows with inboxOutputs show a subtle → inbox link
• Verify the status pill (layout) reconciles within ~10 s after enable/disable
