feat(skills): product-launch-video skill + consolidate motion knowledge into hyperframes-animation (#1745)

* feat(skills): product-launch-video + consolidate motion knowledge into hyperframes-animation

- Add the product-launch-video skill: shot-sequence architecture where each
  visual frame is a time-coded shot sequence picked from a blueprint menu and
  paced to the voiceover (anti-PowerPoint). Includes the frame-worker sub-agent,
  story/visual/motion-design references, and audio/captions/transitions/
  stage-assets/assemble-index scripts.
- Consolidate motion knowledge in hyperframes-animation as the single source of
  truth: promote the updated atomic rules (31 -> 36) and rename product-launch-
  video's archetypes into hyperframes-animation blueprints (13 -> 15, replacing
  the old set). product-launch-video, faceless-explainer, and pr-to-video now
  reference them via ../hyperframes-animation/{rules-index,blueprints-index}.md
  and the rules/blueprints dirs. Fixes the discrete-text-sequence broken links;
  blueprints no longer ship per-id runnable examples, so example references in
  the consumers were dropped.
- Default HeyGen TTS voice to Marcia (deterministic; was the API's first English
  voice, which drifts on catalog re-sort). Override with --voice.
- assemble-index pre-assembly frame guards: auto-repair a sub-comp root missing
  canvas dims; hard-fail on <video>/<audio> inside a sub-comp; hard-fail on a
  timed non-root element missing class="clip" or overlapping same-track clips.
- Lint/CLI: lint media inside sub-compositions as an error; stop false-positive
  caption layout/lint findings; contrast/layout-audit skip elements hidden by an
  invisible ancestor.

* fix(skills): clear CodeQL alerts in assemble-index.mjs

- script/style blanking regex now matches closing tags with trailing
  whitespace (</script >, </style >) — js/bad-tag-filter (high).
- drop the existsSync precheck before reading/repairing a frame file; read
  directly and handle ENOENT, removing the check->write TOCTOU window —
  js/file-system-race (high).

+# constellation-hub — Constellation / Hub + Satellites
+
+**intent**: Labeled/iconned nodes spring into a ring/cluster around a center, then the shot resolves on the core — either by pushing the camera INTO the center (depth-of-field collapsing onto it) or by holding a hub mark while the satellites ORBIT it; the "everything connects to / sits around one center" beat.
+
+**roles served**
+
+- Hook (from `hook-cluster-push-in`): a constellation of tool/app nodes springs into a wide ring, then a sustained camera push-in with depth-of-field resolves on the inner core — "it connects everything / one hub for all your tools."
+- Social_Proof (from `social-proof-orbit-ecosystem`): the product brand mark lands as the center hub and partner logos spring onto a ring and revolve around it — "plugs into / sits at the center of your stack."
+- CTA (from `cta-orbit-collapse`): the ring resolves by COLLAPSE rather than a push-in — category icons drift around an empty central CTA, a cursor click implodes the orbit toward the click point, and the product demo springs OUT of that collapse as the answer (scope → choice → consequence → product).
+- Social_Proof (from `proof-logo-chain`): a persistent center logo accrues proofs — its wordmark decodes, a claim ticker swaps, the logo glides to center, then avatars cascade into orbit with drawn connectors while partner logos scroll the bottom strip; four claims read as one statement.
+
+**duration**: 5–8s (Hook 5–6s · Social_Proof 5–8s · CTA orbit-collapse ~6s)
+
+**shot structure**
+
+Consolidated template — nodes ring a center, then one of two finishers resolves on the core.
+
+- Scene 1 (0.0–~1.5s): `[bg]` (dark/space field, optionally slow-drifting diffused gradient blobs). `[primary nodes]` (circles carrying `[icon]` + label) SPRING-POP in (scale 0→1, ~1.15 elastic overshoot, staggered) arranged in a wide ring/cluster around an empty or marked center `[hub]`.
+- Scene 2 (~0.7–2.5s, overlapping): smaller `[secondary nodes]` (platform / partner-logo chips) pop in staggered with the same elastic spring, filling the gaps; optional thin `[accent]` connector lines / orbit ring draw from hub→nodes. Camera holds.
+- Scene 3 (~2.5–Xs, the resolve): see finisher variant below; lands and HOLDS on the magnified / orbited center to the end.
+
+- Variant — Hook (push-in finisher): from Scene 3, a continuous smooth CAMERA PUSH-IN toward the center inner cluster — inner nodes scale up and stay sharp while outer nodes are pushed toward the edges and progressively BLUR (depth-of-field), background scales up smoothly; holds magnified on the core.
+- Variant — Social_Proof (orbit finisher): the center `[brand mark]` snaps in via a quick 3D rotate that decelerates and settles; a thin `[accent]` orbit ring draws around it; `[N partner badges]` spring onto the ring (staggered overshoot) and revolve CLOCKWISE while staying upright, under a continuous slow camera ZOOM-OUT (ecosystem reveal).
+- Variant — Social_Proof (optional type-push-through opener, prepended before Scene 1): centered `[headline]` types/slides in with a huge transparent-fill OUTLINE copy of the same words behind it; the outline text scales up exponentially toward camera (high-speed dolly / push-through), breaches the frame, then HARD-CUTS to the hub bg of Scene 1.
+
+**motion vocabulary**: staggered elastic spring-pop node entrances (~1.15 overshoot); slow gradient-blob drift; connector-line / orbit-ring draw-on; 3D snap-rotate-settle on the hub mark; continuous camera push-in (inner sharp, outer depth-of-field blur, bg scale-up); clockwise orbital revolve of upright badges; continuous slow camera zoom-out (ecosystem reveal); optional outline-text push-through dolly entry.
+
+**rule mapping** (motion verb → `rules/<id>.md`)
+
+- staggered spring-pop node entrances → `spring-pop-entrance` (elastic overshoot) + `gsap-effects` (stagger recipe); 3D-flip-in flavor → `orbit-3d-entry`
+- ring / cluster layout of nodes around a center → `avatar-cloud-network` (nodes on an elliptical ring + SVG lines to a center)
+- icons on the nodes → `svg-icon-enrichment`
+- connector lines hub→node → `svg-path-draw`
+- orbit-ring draw-on → `svg-path-draw`
+- slow gradient-blob drift → `sine-wave-loop` (idle looped drift)
+- 3D snap-rotate-settle on hub mark → `orbit-3d-entry` (3D-flip entry); technique CSS-3D
+- clockwise orbital revolve of upright badges → `orbit-3d-entry` (continuous elliptical orbit); technique MotionPath
+- camera push-in toward center → `multi-phase-camera` (PUSH-in) + `coordinate-target-zoom` (target the core)
+- background scale-up during push-in → `multi-phase-camera`
+- continuous slow zoom-out (ecosystem reveal) → `multi-phase-camera` (pull-back) / `coordinate-target-zoom`
+- outline-text push-through dolly opener (Social_Proof) → `3d-text-depth-layers` (outline copy behind) + `multi-phase-camera` (push-through)
+- depth-of-field blur on outer nodes during push-in → `depth-of-field-blur` (progressive DOF/focus-falloff blur on the off-center outer nodes while the inner core stays sharp)
+
+**camera modifier**: push-in-with-DOF (Hook) — `multi-phase-camera` PUSH-in targeted via `coordinate-target-zoom` onto the core; the focus-falloff blur half of it is backed by `depth-of-field-blur`. Orbit finisher (Social_Proof) — slow continuous zoom-out via `multi-phase-camera` (pull-back) while satellites revolve.
