release: 0.6.0 — auto-refresh (scheduled rescoring) (#7)

* feat: 0.6.0 task 01 — scheduled rescoring

Adds a 6-hourly GitHub Actions cron that re-runs `bun run seed` and
commits the refreshed `data/rank.db` to `main`. Surfaces the
overall-score delta from the previous rescore on the repo detail
page. Downscoped from the original webhook + queue design — see
tasks/0.6.0/01-scheduled-rescoring.md for the rationale.

Pieces:
- .github/workflows/scheduled-rescore.yml — cron + concurrency
  group + sqlite3-snapshot diff so unchanged-score runs skip the
  commit (last_scored_at churn would otherwise force a binary diff).
- lib/db.ts — new `previous_overall_score REAL` column; the UPSERT
  captures the row's pre-update overall_score on every rescore.
- lib/types/db.ts — extracted shared row-shape types out of
  lib/db.ts (RepoRow, LeaderboardRow, …). Consumers now import from
  @/lib/types/db.
- components/RepoHero.tsx — inline `+N.N pts` / `-N.N pts` next to
  "Last scored" in text-ok / text-bad; aria-label carries the
  previous absolute score for screen readers.
- scripts/seed-list.ts — 16 new seed repos across JS/TS, Python,
  Rust, Go, Java, Ruby, and .NET so the cron has more material.
- data/rank.db — re-seeded against the new schema.

SEO + polish bundled in:
- app/layout.tsx — googleBot robots directives
  (max-image-preview=large, max-snippet=-1, max-video-preview=-1)
  and OG image dimensions corrected to the actual file size
  (2312×924).
- components/Panel.tsx — PanelHeading rendered as h2 (was h3) so
  every page has a clean h1 → h2 heading hierarchy.
- app/sitemap.ts — privacy / terms now use a fixed
  LEGAL_LAST_UPDATED date instead of `now`, so legal pages don't
  churn lastmod on every deploy.

Docs sync:
- AGENTS.md, README.md, CONTRIBUTING.md, methodology FAQ, roadmap
  entry, tasks/0.5.0/02, tasks/1.0.0/01-02, and the SessionStart
  hook updated to reference the scheduled-rescore cron instead of
  the deferred webhook design.

APP_VERSION stays at 0.5.0 — 0.6.0 still has task 02 (alternatives
v2 embeddings) outstanding, so no changelog bucket yet.

* chore: cut 0.6.0 — auto-refresh

- Bump APP_VERSION / package.json to 0.6.0 and add the 0.6.0 changelog
  entry (scheduled rescoring + repo-page score delta + 16 new seeds).
- Remove 0.6.0 from lib/roadmap.ts (released) and mark 0.6.0/02
  (alternatives-v2 embeddings) deferred to backlog with the rationale
  and lighter-weight options.
- Sync AGENTS.md status block, .claude/settings.json SessionStart
  banner, tasks/0.6.0/README.md, and the stale 0.3.0 references that
  pointed at the deferred v2 upgrade.
- Add a dedicated home-route opengraph-image.tsx (1200x630) and add a
  `deferred` status to tasks/README.md.

* chore: consolidate OG/twitter metadata defaults + auto-wire twitter cards

Extract OG_DEFAULTS and TWITTER_DEFAULTS in lib/version.ts and spread them
into every page's metadata — Next.js shallow-merges these objects, so
defaults must be re-spread on every page. Drop the inline /demo/light.png
override from the root layout in favour of the auto-wired
app/opengraph-image.tsx, and add matching twitter-image.tsx re-exports at
app/ and app/repo/[id]/ so the Twitter card uses the same generated image.

feat: version 0.5.0 (#5)

* feat: 0.5.0 task 02 - GitHub Action for score

* feat: 0.5.0 task 03 - agent skill

Ship the portable agent skill that scores the user's current repo locally
and recommends a model class. Self-contained: vendored scorer, no service
dependency, works offline — same property as task 02's PR-diff Action.

- Sibling repo `agent-friendly-skill` (v0.1.1, floats `v0`) ships SKILL.md
  + ncc-bundled dist/index.js. Vendored into this repo via
  `npx skills add hsnice16/agent-friendly-skill#v0`; skills-lock.json pins
  ref + content hash so the bundle is reproducible.
- New /skill SEO landing page: install command, score → model mapping,
  optional SessionStart hook snippets for Claude Code + Codex, FAQ, and
  JSON-LD (BreadcrumbList + SoftwareApplication + FAQPage).
- README "Public API" section documents /api/score for external integrators
  (siblings vendor the scorer; they don't call this at runtime).
- AGENTS.md "Sibling repos" mirror discipline now covers both action and
  skill; SIBLING_VERSION in lib/version.ts is the single-source pin that
  drives ACTION_USES, SKILL_INSTALL_CMD, and the #v0 ref in skills-lock.json.
- Layout footer reorganised into Primary + Tools columns; nav surfaces
  /action and /skill; sitemap and /llms.txt include /skill.
- Panel + CopySnippet gain a tone vocabulary (warn / info / tip) so the
  install card, hook snippets, and per-page CTAs share styling.
- Bundled along: gitignore-aware size signal (uses ignore@7.0.5), tests
  for both .gitignore patterns and the baseline ignore set.

* feat: version 0.5.0

Release prep: bump version (lib/version.ts, package.json, README badge),
add changelog entry summarising the score-diff GitHub Action and the
portable agent skill, mark tasks/0.5.0 done and drop the descoped
history-aware-signals task, prune 0.5.0 from the live roadmap.

Also lands SEO breadcrumbs on About/Changelog/Methodology/Packages/Roadmap
via a shared BreadcrumbJsonLd component, extends sitemap with package
routes, surfaces top scored packages per registry in /llms.txt, and
refreshes the SessionStart hook + cross-repo mirroring note on the
feature-request template.
