feat(hyperframes): land HTML-in-Canvas across web + skills (#866)
* feat(hyperframes): land HTML-in-Canvas across web + skills

Ships HTML-in-Canvas as a first-class HyperFrames video path:
- 7 new video prompt templates (liquid glass, iPhone+MacBook, portal,
  shatter, magnetic, liquid background, text-cursor reveal).
- skills/hyperframes/references/html-in-canvas.md, surfaced via
  SKILL.md description+triggers and the system-prompt pre-flight
  references list.
- ChatPane starter prompts now branch by project kind and video model,
  so the hyperframes-html surface shows HTML-in-canvas-shaped prompts
  instead of the generic prototype trio.
- NewProjectPanel propagates a picked template's model+aspect onto
  the project, and defaults videoModel to hyperframes-html when the
  hyperframes skill resolves for the video tab.

Polish bundled in the same branch:
- DesignFilesPanel empty state becomes a centered pill with a "New
  sketch" CTA; designFiles.empty copy simplified across 19 locales.
- Topbar project title + meta render on one baseline row separated
  by a middot.
- scripts/seed-test-projects.ts hardens daemon URL discovery against
  pnpm engine warnings on stdout.

* fix(new-project): preserve explicit video model choice across tab revisits

Latch a videoModelTouched guard once the user picks a model via the
dropdown or via a template that declares one, so the hyperframes-html
auto-default no longer silently overwrites the override when the Video
tab is re-entered.

Generated-By: looper 0.6.1 (runner=fixer, agent=claude-code)

* fix(i18n): register hyperframes html-in-canvas templates, category, and tags

Adds the seven new prompt-template ids, the "VFX / HTML-in-Canvas"
category, and the new tag set to the de/ru/fr i18n bundles so the
e2e localized-content coverage test passes.

* fix(daemon): inject html-in-canvas preflight for hyperframes runs

The contracts-side derivePreflight() learned about
references/html-in-canvas.md when this PR landed, but the daemon
copy at apps/daemon/src/prompts/system.ts kept the older five-ref
allowlist. server.ts:4138 wires composeSystemPrompt from the
daemon copy into live chat runs, so the main HyperFrames flow this
PR is meant to improve still wasn't auto-injecting the preflight
directive in production.

Mirror the html-in-canvas case into the daemon composer and lock it
behind a daemon-side test so the two copies cannot drift again on
this reference. The broader live-artifact preflight gap (artifact-
schema / connector-policy / refresh-contract) is pre-existing drift
and is intentionally out of scope here.

* fix(web): restyle designs empty state as centered card on grid backdrop

Swap the horizontal pill for a stacked card and add a faint grid backdrop
so the empty designs surface reads as an intentional canvas rather than a
gap. Title now wraps instead of truncating; container is taller.

* fix(new-project): pin skillId to hyperframes when videoModel is hyperframes-html

When the Video tab resolves its skill it used to fall back to `list[0]?.id`
if no skill declared `default_for: video`. That list is built from an
unsorted `readdir()` in apps/daemon/src/skills.ts, so a freshly mounted
project could land on `video-shortform` even when the user had explicitly
chosen the HyperFrames-HTML model (or one of the new
`hyperframes-html-in-canvas-*` templates). The agent then ran without the
hyperframes SKILL body or its `references/html-in-canvas.md` preflight —
the exact regression PR #866 was meant to land.

`skillIdForTab` now pins to `hyperframes` whenever the current video model
is `hyperframes-html`, regardless of discovery order. Added a unit test
that mounts both `video-shortform` and `hyperframes` (with hyperframes
last, simulating the bad readdir order) and asserts the create payload
routes through `hyperframes`.

"prompt": "Build a 20-second HyperFrames composition (1920×1080, 30fps) titled \"liquid-glass-landing-reveal\". Pull the catalog block first: `npx hyperframes add vfx-liquid-glass` (or `npx hyperframes add html-in-canvas` to grab the full set).\n\nVisual identity: deep-space canvas #0a0d14, single warm accent #ff8a4c for refraction tint, secondary cool #6cf3c0 for chromatic edge highlights, off-white text #f5f7fa. Display face: \"Migra\" 140px for the headline; body \"Söhne\" 24px; mono \"JetBrains Mono\" 18px. Tabular-nums on any numerals.\n\nTwo nested compositions:\n\n1. `landing-source` — a `<canvas layoutsubtree width=\"1920\" height=\"1080\">` containing the actual product landing-page DOM: a tall hero (\"Ship faster. Stay calm.\"), a 3-column feature grid with rounded cards using `backdrop-filter: blur(24px)`, a soft radial accent glow behind the headline, and a CTA pill (\"start free\"). Real CSS, real web fonts — this gets captured live by the WebGL pass.\n2. `theater` — the WebGL canvas that runs the vfx-liquid-glass shader on the captured texture.\n\nTimeline (single root composition, paused: true, registered as window.__timelines.main, data-duration=20):\n\n0.06.0s ENTRY — voronoi cells start fully fractured at scale 1.6, opacity 0.2, with strong chromatic aberration (0.04 offset). Easing: expo.out. Cells coalesce inward, refraction strength tapers from 1.0 → 0.18, parallax reveals the underlying landing-page shot.\n\n6.013.5s SETTLE — full landing page resolves crisp behind a thin glass sheen. Add a slow lateral parallax (drift the texture x by 24px over 7s, ease sine.inOut). Tween a subtle highlight sweep across the hero using the `shimmer-sweep` component at 9.0s.\n\n13.520.0s OUTRO — gentle re-fracture: refraction strength 0.18 → 0.42, voronoi scale 1.0 → 1.08, slight rotation 0 → -2deg, opacity hold. Final 0.6s fades the entire theater canvas to black via the root container only — never animate the source DOM out.\n\nFeature detection (mandatory): inside the theater script tag, before instantiating Three.js, check `('layoutSubtree' in document.createElement('canvas')) && typeof CanvasRenderingContext2D.prototype.drawElementImage === 'function'`. If false, hide the theater canvas and let the source DOM display directly — the rendered MP4 always has the flag enabled, but Studio preview without it must not show black.\n\nNon-negotiables: deterministic motion (seeded mulberry32 if any noise needed), no Math.random / Date.now, no `repeat: -1`, no async timeline construction. All entrances via `gsap.from()` against the hero CSS layout. Run `npx hyperframes lint` and `npx hyperframes inspect --samples 12 --at 2,4,6,9,13,17` before render. Output: `liquid-glass-landing-reveal.mp4`.",
