Bring the living docs current with the recency-bounded auto-summarize + sparse
honesty + feed IA bundle (ADR-020):
- requirements (BDD): summarize_mode.feature — auto now summarizes RECENT new
videos; added a scenario for older videos (listed, on-demand), recency note.
- architecture.md: summarization-mode + new list-surface paragraph; scheduler
diagram + two-path table + three-phase pass now show the recency pre-filter;
dropped stale "Summarize now".
- data-model.md: auto_summarize is recent-only, older on-demand.
- README.md: one-line recency note on the serve scheduler.
- ui-spec.md: appended the as-built ADR-020 row (supersedes earlier copy/sort).
- specs/{video-card-states,newest-first-ordering,scheduled-discovery}.md:
superseded/extended banners pointing at ADR-020 (kept as design records).
Docs-only; task check green.

The card shows two verbs ("Try now" for rate-limited, "Summarize" for pending)
for one user intent, and — the real bug — a no-captions video falls into the
pending branch and wrongly shows a Summarize button that can only fail. Spec
collapses to one quiet "Summarize now" verb wherever a nudge is possible (both
handlers unchanged underneath), adds an honest no-button "No transcript
available" state, and keeps the card status-first (buttons are exceptions in auto
mode). View-layer only.
