Changelog page from keel Releases + Get Started refresh (browser setup, WAL) + land EN revision, verify share-readiness

[eaitbrahim]

What

Three workstreams, one goal: the site tells the engine's current story and the trilingual revision is fully live.

1. Changelog page (like docs.jesse.trade/docs/changelog)

• New page /{en,ar,fr}/changelog/ fed at build time from CodeGateSoftware/keel/releases — extend scripts/fetch-release.mjs to fetch the release list and write each body into a (gitignored) content collection, rendered by Astro's markdown pipeline (same pattern as the engine docs, no new dependency).
• Design per Jesse's model, in our own style: one page, newest first, per-release heading vX.Y.Z — date with anchors, an on-this-page version TOC, link to GitHub per release.
• Honesty: release notes stay in English (canonical); ar/fr pages translate the chrome and say so. Graceful fallback to a Releases link when the fetch yields nothing. Nav entry after News.

2. Get Started refresh

Engine main (25 commits ahead of v0.10.0) added: double-clickable macOS app (keel.app), keel serve browser view, first-run checklist + credential form with OS-keychain storage, market data as a background job, attest/promote from the browser (#469), and SQLite WAL mode (#470). None of that is in a release yet — v0.10.0 ships wheels only. The Get Started copy must say exactly that: browser-first setup is on main and lands in the next release; today's download remains the terminal-first path. AR/FR mirrored, revs bumped.

3. Land the EN revision + verify

• PRs i18n(ar): revise every page's Arabic into Modern Standard Arabic #36 (AR → MSA) and i18n(fr): revise every page into modern journalistic French #40 (FR → journalistic) are merged; docs(i18n): copy-edit the English to newspaper style #39 (EN → newspaper style) is still open — review and land it.
• Review the merged diffs, deploy main, and run the full pre-share verification sweep (all pages × 3 locales, changelog content + hreflang + sitemap, analytics beacon, Install/News live data).

Acceptance

• /en/changelog/ (+ar/fr) live, listing all releases newest-first with anchors and TOC
• Header nav links the changelog in all locales; Install page links the full history
• Get Started mentions browser setup + WAL honestly (on main / next release)
• docs(i18n): copy-edit the English to newspaper style #39 merged; trilingual revision deployed and verified
• Site passes the readiness sweep; this issue closes the remaining pre-share gaps

All three workstreams landed, deployed, and verified.

1. Changelog page — PR #42. /{en,ar,fr}/changelog/ renders all 25 releases newest-first, straight from GitHub Releases at build time (fetch-release.mjs writes a gitignored content collection; engine-docs pattern, no new dependency). Version headings with anchors (#v0-10-0), on-this-page TOC, latest chip, per-release GitHub link; release-body headings demoted one level under each version heading. ar/fr translate the chrome and say the notes are English. Nav link after News ×3; Install links the full history.

2. Get Started refresh — PR #43. New Install section “Work from the browser — on main, in the next release”: macOS app + keel serve, first-run checklist, keychain credentials, background market data, browser attest/promote, WAL — all of it honestly framed as unreleased (engine main is 25 commits ahead of v0.10.0, which ships wheels only). Mirrored in AR/FR; revs → 2026-08-20.8.

3. EN revision landed + verified. PR #39 reviewed (style-only, meaning preserved, revs synced) and merged — the trilingual MSA/journalistic/newspaper revision is now fully on main.

Deploy + verification (run 32429950212): all 30 localized pages 200; changelog 25 anchors + hreflang ×4 + TOC + chip + sitemap ×3; nav links ×3; browser section live in EN/AR/FR; analytics beacon embedded; demoted headings confirmed in production HTML.

Known non-blocker: Sonar's duplication gate (4.4% on #42) is the documented Automatic-Analysis false positive on tri-locale siblings — same class as #36/#40/#39. The durable fix still needs either the dashboard Duplication Exclusion (src/i18n/**) or CI-based analysis with SONAR_TOKEN.
