site: feeds everywhere + programmatic surface

Feeds: JSON Feed 1.1 at /feed.json, per-category and per-tag RSS at
/categories/<name>/rss.xml and /tags/<name>/rss.xml alongside the main
/rss.xml — all from a shared src/lib/feed.ts item source. Category/tag
pages advertise their scoped feed via autodiscovery; new /feeds/
directory page (footer-linked) lists every feed with counts; RSS feeds
gain an atom:link self reference and a feed.xsl stylesheet so they
render readably in browsers.

Programmatic readers: build-generated /llms.txt (site map with every
review/bundle/post), SearchAction on the WebSite JSON-LD wired to
/search/?q=, and a "For robots" section on /feeds/ documenting
search.json, llms.txt, the sitemap, and JSON-LD coverage.

 ## July 2026
 
+- Feeds for everything: alongside the existing `/rss.xml`, add a JSON Feed 1.1 at `/feed.json`, per-category RSS at `/categories/<name>/rss.xml`, and per-tag RSS at `/tags/<name>/rss.xml` — all derived from a shared `src/lib/feed.ts` item source (reviews + posts + bundles, same visibility rules as the site). Category/tag pages advertise their scoped feed via `<link rel="alternate">` autodiscovery; a new `/feeds/` directory page (linked from the footer) lists every feed with entry counts; every RSS feed carries an `atom:link` self reference and renders as a readable page in browsers via `public/feed.xsl`
+- Programmatic-reader pass: build-generated `/llms.txt` (llmstxt.org format — site description, feed/endpoint map, and every review, bundle, and post with one-line descriptions), `SearchAction` on the home-page `WebSite` JSON-LD wired to `/search/?q=`, and a "For robots" section on `/feeds/` documenting `search.json`, `llms.txt`, the sitemap, and JSON-LD coverage
 - Autonomous pipeline overhaul: new `/daily-pipeline` skill chains capture → bundle → review graduation → pick-of-the-day → build → commit → push and ends with a digest; `daily-finds` gains a score-and-shortlist stage (up to 12 `shortlist: true` finds per run, top 1-3 flagged as review candidates), feed-first fetching (`fetch: "feed"` + `feedUrl` in sources.json), cadence-aware scanning, and authority to apply mechanical source maintenance itself; `build-bundle`/`cluster-bundles`/`build-review` gain unattended `auto` modes (publish + log instead of pausing for confirmation), and `build-bundle weekly` writes a date-based "week's catch" so shortlisted finds never sit unbundled for weeks
 - Review heroes are now auto-discovered: `src/lib/hero.ts` globs `reviews/*/hero.<ext>` (images and `hero.mp4`), so a new review needs no registration — only legacy non-`hero`-named assets remain as explicit overrides; both hero globs also accept `.avif`
 - Pick of the day moves from a hardcoded constant in `src/pages/index.astro` to `src/data/pick.json` (falls back to the latest review); the dev-mode "Make today's pick" button writes the JSON file
