feat: consolidate all Anthropic plugins into ECC v2.0.0

Ports functionality from 10+ separate plugins into ECC so users only
need one plugin installed. Consolidates: pr-review-toolkit, feature-dev,
commit-commands, hookify, code-simplifier, security-guidance,
frontend-design, explanatory-output-style, and personal skills.

New agents (8): code-architect, code-explorer, code-simplifier,
comment-analyzer, conversation-analyzer, pr-test-analyzer,
silent-failure-hunter, type-design-analyzer

New commands (9): commit, commit-push-pr, clean-gone, review-pr,
feature-dev, hookify, hookify-list, hookify-configure, hookify-help

New skills (8): frontend-design, hookify-rules, github-ops,
knowledge-ops, lead-intelligence, oura-health, pmx-guidelines, remotion

Enhanced skills (8): article-writing, content-engine, market-research,
investor-materials, investor-outreach, x-api, security-scan,
autonomous-loops — merged with personal skill content

New hook: security-reminder.py (pattern-based OWASP vulnerability
warnings on file edits)

Totals: 36 agents, 69 commands, 128 skills, 29 hook scripts

+description: Embedding videos in Remotion - trimming, volume, speed, looping, pitch
+metadata:
+  tags: video, media, trim, volume, speed, loop, pitch
+---
+
+# Using videos in Remotion
+
+## Prerequisites
+
+First, the @remotion/media package needs to be installed.  
+If it is not, use the following command:
+
+```bash
+npx remotion add @remotion/media # If project uses npm
+bunx remotion add @remotion/media # If project uses bun
+yarn remotion add @remotion/media # If project uses yarn
+pnpm exec remotion add @remotion/media # If project uses pnpm
+```
+
+Use `<Video>` from `@remotion/media` to embed videos into your composition.
+
+```tsx
+import { Video } from "@remotion/media";
+import { staticFile } from "remotion";
+
+export const MyComposition = () => {
+  return <Video src={staticFile("video.mp4")} />;
+};
+```
+
+Remote URLs are also supported:
+
+```tsx
+<Video src="https://remotion.media/video.mp4" />
+```
+
+## Trimming
+
+Use `trimBefore` and `trimAfter` to remove portions of the video. Values are in seconds.
+
+```tsx
+const { fps } = useVideoConfig();
+
+return (
+  <Video
+    src={staticFile("video.mp4")}
+    trimBefore={2 * fps} // Skip the first 2 seconds
+    trimAfter={10 * fps} // End at the 10 second mark
+  />
+);
+```
+
+## Delaying
+
+Wrap the video in a `<Sequence>` to delay when it appears:
+
+```tsx
+import { Sequence, staticFile } from "remotion";
+import { Video } from "@remotion/media";
+
+const { fps } = useVideoConfig();
+
+return (
+  <Sequence from={1 * fps}>
+    <Video src={staticFile("video.mp4")} />
+  </Sequence>
+);
+```
+
+The video will appear after 1 second.
+
+## Sizing and Position
+
+Use the `style` prop to control size and position:
+
+```tsx
+<Video
+  src={staticFile("video.mp4")}
+  style={{
+    width: 500,
+    height: 300,
+    position: "absolute",
+    top: 100,
+    left: 50,
+    objectFit: "cover",
+  }}
+/>
+```
+
+## Volume
+
+Set a static volume (0 to 1):
+
+```tsx
+<Video src={staticFile("video.mp4")} volume={0.5} />
+```
+
+Or use a callback for dynamic volume based on the current frame:
+
+```tsx
+import { interpolate } from "remotion";
+
+const { fps } = useVideoConfig();
+
+return (
+  <Video
+    src={staticFile("video.mp4")}
+    volume={(f) =>
+      interpolate(f, [0, 1 * fps], [0, 1], { extrapolateRight: "clamp" })
+    }
+  />
+);
+```
+
+Use `muted` to silence the video entirely:
+
+```tsx
+<Video src={staticFile("video.mp4")} muted />
+```
+
+## Speed
+
+Use `playbackRate` to change the playback speed:
+
+```tsx
+<Video src={staticFile("video.mp4")} playbackRate={2} /> {/* 2x speed */}
+<Video src={staticFile("video.mp4")} playbackRate={0.5} /> {/* Half speed */}
+```
+
+Reverse playback is not supported.
+
+## Looping
+
+Use `loop` to loop the video indefinitely:
+
+```tsx
+<Video src={staticFile("video.mp4")} loop />
+```
+
+Use `loopVolumeCurveBehavior` to control how the frame count behaves when looping:
+
+- `"repeat"`: Frame count resets to 0 each loop (for `volume` callback)
+- `"extend"`: Frame count continues incrementing
+
+```tsx
+<Video
+  src={staticFile("video.mp4")}
+  loop
+  loopVolumeCurveBehavior="extend"
+  volume={(f) => interpolate(f, [0, 300], [1, 0])} // Fade out over multiple loops
+/>
+```
+
+## Pitch
+
+Use `toneFrequency` to adjust the pitch without affecting speed. Values range from 0.01 to 2:
+
+```tsx
+<Video
+  src={staticFile("video.mp4")}
+  toneFrequency={1.5} // Higher pitch
+/>
+<Video
+  src={staticFile("video.mp4")}
+  toneFrequency={0.8} // Lower pitch
+/>
+```
+
+Pitch shifting only works during server-side rendering, not in the Remotion Studio preview or in the `<Player />`.
