chore: release v0.29.3

[mmcky]

v0.29.3 — patch. Promotes [Unreleased] for three merged PRs:

PR	What it ships	Affects
#328	fr glossary v1.1 → v1.2: Namespace → Espace de nommage, Heads (coin toss) → Face, the Standard normal context refined	French syncs, once @v0 moves — the reason for this release
#322	Harness reset lists open PRs with --limit 200 and stops if any survive	Release gate only
#323	rate-check.sh, release step 4b	Release gate only

Version bumped in package.json / package-lock.json; CHANGELOG promoted with a fresh [Unreleased] header; .dev/STATE.md entry. No source change; dist-action/ rebuilds byte-identical (engineVersion is a runtime read of package.json). npm test 1590/1590.

After merge: tag v0.29.3 → §4a E2E gate on the tag and the 4b rate check (the first gate to run both new harness changes) → move v0.29 and v0 → @v0 smoke → GitHub release. Tallies will be posted here.

The French edition is already consistent with the new glossary (QuantEcon/lecture-python-programming.fr#81, merged 2026-09-23), so the first French sync after the tags move should show no terminology churn.

§4a gate on the v0.29.3 tag (16e50f6): passed. Released.

	zh-cn	fa	ml
sync runs succeeded	28 / 28	28 / 28	28 / 28
translation PRs delivered	28	28	28
verdicts at engineVersion: 0.29.3	28 / 28	28 / 28	28 / 28

Census 9/9 workflows at @v0.29.3; 28 source PRs; 84/84 sync runs, none failed. Scenario 17 (new-document-toc) delivered game-theory.md, its state file and _toc.yml on all three lanes (test-translation-sync.zh-cn#981, .fa#367, .ml#274). The reset's new post-reset check (#322) ran clean — no survivors, every lane at exactly 28.

§4b rate check (rate-check.sh --ref v0.29.3, first release to run it): game-theory.md refused 0/12 on zh-cn, fa and ml.

Checklist 5: v0.29 and v0 moved 5f74d74 → 16e50f6. @v0 smoke (scenario 01): 3/3 sync runs succeeded; verdicts report engineVersion: 0.29.3, engineRef: v0 on all three lanes (test-translation-sync.zh-cn#991, .fa#375, .ml#280). Checklist 6: GitHub release published, title = the tag.

French syncs now use glossary v1.2; the edition was aligned beforehand (QuantEcon/lecture-python-programming.fr#81).
