fix(scheduler): derive rotation offset from wall-clock, not a reset-on-restart counter

The lead-user rotation used an in-memory pass counter reset to 0 on every pod
restart, so the first-listed user always re-took the lead after a restart — a
deploy-heavy session re-starved the last user (the pilot stalled at 2 summaries
because each deploy reset his every-other-pass lead before the 2h tick fired).
Derive the offset from wall-clock (floor(now/interval)) so it advances with real
time and is identical across restarts: rotation stays fair however often the pod
bounces.

+## ADR-025 — Honest, state-aware foreground summarization status
+
+**Status:** Accepted (2026-06-10). **Pillar B of the manual-mode UX work** (Pillar A, foreground
+fetch priority, is a separate follow-up). Builds on ADR-014 (the rate limit the UX must make
+legible).
+
+**Context.** Clicking "Summarize" spawned a background goroutine and polled `/status`, which
+returned only two states: the spinner (in-flight) or the normal card (done). But the web
+`ProcessVideo` only recorded an outcome on *success* — a 429'd or caption-less click left
+`transcript_status` unset, so the next poll silently reverted to the "Summarize" button. The
+user saw either an endless spinner or a button that did nothing useful when clicked again. The
+binding constraint (YouTube's caption rate limit) was completely invisible.
+
+**Decision.**
+1. **Record every outcome on the web path**, mirroring the runner: `ProcessVideo` stamps
+   `rate_limited` / `none` / `fetched`. A rate-limited video keeps its requested flag so the
+   background sweep retries it; `none` and `fetched` are terminal.
+2. **`/status` is state-aware**: summarized → summary card; in-flight → working spinner;
+   `rate_limited` → a calm "waiting, will retry" card that keeps polling (every 30s) so the
+   summary appears on its own when the retry lands — the user never clicks again;
+   `none` → a terminal "no captions" card with no poll and no dead-end button.
+3. **Charm status text** (Claude-Code / Crush inspired): the working spinner cycles playful,
+   tapir-themed gerunds ("Chewing the cud…", "Munching leaves…", "Distilling the gist…") via
+   CSS only — no JS, keeping the HTMX/no-JS ethos. Decorative (aria-hidden) with a stable
+   `role=status` line for assistive tech.
+
+**Principle.** When the system cannot be fast (throttled IP), it is at least honest, and it
+self-resolves without making the user retry. Honesty is the load-bearing half — Pillar A's
+priority lane only improves the odds of a fast slot; it cannot beat an already-hot IP.
+
+**Reversibility.** Pure transport-layer + view change over the unchanged engine/ports. No
+schema change (reuses `transcript_status` from migration 007).
