v1.56.0

[1.56.0] — 2026-05-19

feat(ux): LOW-priority polish bundle — UX-9 / UX-10 / UX-11 / UX-12 (one grouped minor release).

✨ Features

• UX-9 — #/cv breadcrumb (visual hierarchy): the page title is demoted to a quiet uppercase .cv-breadcrumb chip and the loud page-subtitle paragraph moves to the <h1> title tooltip, so the user's CV (their name, rendered in the preview) owns the visual space. The F-V54-A invariant is intact — still exactly one <h1>, still .page-title (the router focus target); only its weight changed.
• UX-10 — honest cost ballpark (trust/feedback): a new shared UI.providerCostHint(t) helper renders next to ⚡ Run live on #/auto, #/evaluate, #/deep and every #/<mode>. It reuses GET /api/status/providers (v1.55.3): with a key it shows "Estimated cost: OpenAI gpt-5-codex · ~$0.04/eval" (order-of-magnitude, deliberately "~"); with no key it states plainly that ⚡ Run live copies a manual prompt at no API cost. Fail-soft (hidden when offline).
• UX-11 — #/help TOC auto-jump (aesthetic/flow): when the TOC filter narrows to exactly one section, the page smooth-scrolls there after a 300ms idle (debounced — mid-typing keystrokes never yank the page; never fires for 0 or >1 matches), reusing the same scroll+focus path as a TOC click.
• UX-12 — #/dashboard first-paint a11y (accessibility): on the very first SPA paint the landing view's <h1> is now made programmatically focusable (tabindex="-1") so screen-reader / heading navigation lands on it, and #content stays aria-live="polite" so the heading is announced on boot — without stealing focus (that would fight the skip-link, the deliberate v1.41.0 behaviour). Only subsequent route changes move focus. (Note: UX-12 as originally specified — "call focusNewView() on boot" — conflicted with the v1.41.0 skip-link decision; resolved conservatively to satisfy the a11y intent without the regression.)
• New i18n keys cost.estimate, cost.manual ×8 locales; new token-based .cv-breadcrumb / .cost-hint CSS.

🧪 Tests

• 4 new CI-isolated source-static suites — tests/cv-breadcrumb.test.mjs (3), tests/run-cost-line.test.mjs (4), tests/help-toc-autoscroll.test.mjs (4), tests/dashboard-initial-focus.test.mjs (3): single-h1 + breadcrumb class; shared helper exported + fail-soft + present in all 4 views + cost.* ×8; debounced exactly-1-match jump gated; tabindex-before-guard ordering + focus-after-guard + #content aria-live. The pre-existing cv-single-h1 and help-nav-a11y locks were updated for the new (invariant-preserving) code. 800 → 813. Live Playwright probe of all four (no-key fixture): single h1 13px breadcrumb, cost hint manual note, TOC→1 narrow, h1 tabindex=-1 + aria-live polite, 0 console errors.
