chore: delete podcast feature

CHANGELOG.md

@@ -26,6 +26,7 @@ the archive; if it broke production, it belongs in `docs/incidents/`. See
 - **Ops** — deploys no longer run a full SSG rebuild (~25 min of CPU, held the only runner): it runs nightly after the backup; `rebuild_ssg` input on a manual deploy for releases that change SEO rendering; health check alarms at 36h stale (was 72h) — infra
 - **Security** — hardening from the architecture review: stored files are served with a sandbox CSP + nosniff (nginx and the API), `/internal/*` is refused at nginx and its network check is one tested helper, two copyrighted test PDFs removed (image-only test now uses a generated PDF) — backend, infra
 - **Security** — connect keys get the same account-route scope as OAuth tokens; per-IP rate limits group IPv6 by /64; nginx rate-limit zones key on the client address — api, infra
+- **Cleanup** — podcast feature deleted: worker, script builder, ffmpeg audio assembly, `/books/{slug}/podcast` + `/admin/podcasts` endpoints, `podcast.script` route + eval, web book-page player, admin Generate button; `podcast_generation_jobs` dropped (`DropPodcast`), ffmpeg removed from the Worker image; stored mp3s left on disk — backend, admin, web
 - **Discover** — the "Learn a language by reading real books" card no longer fills a small screen: it scrolls with the page under the search box, and a × hides it for good (`onboarding.startReadingCard.dismissed`) — closed-test report, Unihertz Titan 2 — mobile
 - **Docs** — docs checked against the code before the architecture review: STATUS, CLAUDE.md, architecture + system docs, ADR status lines, feature/ops/dev docs; `[Unreleased]` cut into deploy-date headings; stale plans marked historical — docs
 - **Ops** — health check hits `/api/health` and asserts `"healthy"` (`/health` was the SPA's 200); `pg_dump | gzip` under pipefail + dump-trailer check (backup, pre-deploy); daily disk alarm at 85% (`/`, docker root); deploy polls the API instead of `sleep 30` and fails on unhealthy services; host Claude CLI pollers run from a temp dir with `--tools ""`; deploy restarts `quality-poller` — infra
