feat: port remotion-video-creation skill (29 rules), restore missing files

New skill:
- remotion-video-creation: 29 domain-specific Remotion rules covering 3D/Three.js,
  animations, audio, captions, charts, compositions, fonts, GIFs, Lottie,
  measuring, sequencing, tailwind, text animations, timing, transitions,
  trimming, and video embedding. Ported from personal skills.

Restored:
- autonomous-agent-harness/SKILL.md (was in commit but missing from worktree)
- lead-intelligence/ (full directory restored from branch commit)

Updated:
- manifests/install-modules.json: added remotion-video-creation to media-generation
- README.md + AGENTS.md: synced counts to 139 skills

Catalog validates: 30 agents, 60 commands, 139 skills.

+
+# Charts in Remotion
+
+You can create bar charts in Remotion by using regular React code - HTML and SVG is allowed, as well as D3.js.
+
+## No animations not powered by `useCurrentFrame()`
+
+Disable all animations by third party libraries.  
+They will cause flickering during rendering.  
+Instead, drive all animations from `useCurrentFrame()`.
+
+## Bar Chart Animations
+
+See [Bar Chart Example](assets/charts/bar-chart.tsx) for a basic example implmentation.
+
+### Staggered Bars
+
+You can animate the height of the bars and stagger them like this:
+
+```tsx
+const STAGGER_DELAY = 5;
+const frame = useCurrentFrame();
+const {fps} = useVideoConfig();
+
+const bars = data.map((item, i) => {
+  const delay = i * STAGGER_DELAY;
+  const height = spring({
+    frame,
+    fps,
+    delay,
+    config: {damping: 200},
+  });
+  return <div style={{height: height * item.value}} />;
+});
+```
+
+## Pie Chart Animation
+
+Animate segments using stroke-dashoffset, starting from 12 o'clock.
+
+```tsx
+const frame = useCurrentFrame();
+const {fps} = useVideoConfig();
+
+const progress = interpolate(frame, [0, 100], [0, 1]);
+
+const circumference = 2 * Math.PI * radius;
+const segmentLength = (value / total) * circumference;
+const offset = interpolate(progress, [0, 1], [segmentLength, 0]);
+
+<circle r={radius} cx={center} cy={center} fill="none" stroke={color} strokeWidth={strokeWidth} strokeDasharray={`${segmentLength} ${circumference}`} strokeDashoffset={offset} transform={`rotate(-90 ${center} ${center})`} />;
+```
