## Summary Add the actual Studio timeline editing layer on top of the preview/runtime foundation. This PR includes: - drag-to-move clips across time and tracks - left/right resize handles with media-aware trim persistence - edge auto-scroll and edge track creation while dragging - selector-based source patching for `data-start`, `data-duration`, `data-track-index`, `z-index`, and media trim attributes - timeline UI cleanup, theming, hover/drag states, and the `Copy Prompt` action ## Why This PR Is Separate This is the user-facing editing behavior. It depends on the preview/runtime fixes in the base PR, but it is much easier to review once that plumbing is isolated. ## Verification - `bun run --filter @hyperframes/studio test` - `bun run --filter @hyperframes/studio typecheck` - `bunx oxlint packages/studio/src/App.tsx packages/studio/src/components/nle/NLELayout.tsx packages/studio/src/player/components/EditModal.tsx packages/studio/src/player/components/Timeline.tsx packages/studio/src/player/components/TimelineClip.tsx packages/studio/src/player/components/timelineEditing.ts packages/studio/src/player/components/timelineEditing.test.ts packages/studio/src/player/components/timelineTheme.ts packages/studio/src/player/components/timelineTheme.test.ts packages/studio/src/utils/sourcePatcher.ts packages/studio/src/utils/sourcePatcher.test.ts` - `bunx oxfmt --check packages/studio/src/App.tsx packages/studio/src/components/nle/NLELayout.tsx packages/studio/src/player/components/EditModal.tsx packages/studio/src/player/components/Timeline.tsx packages/studio/src/player/components/TimelineClip.tsx packages/studio/src/player/components/timelineEditing.ts packages/studio/src/player/components/timelineEditing.test.ts packages/studio/src/player/components/timelineTheme.ts packages/studio/src/player/components/timelineTheme.test.ts packages/studio/src/utils/sourcePatcher.ts packages/studio/src/utils/sourcePatcher.test.ts` ## Browser Proof - verified timeline drag / resize / trim flows in Studio with `agent-browser` - verified preview hot-refresh behavior without iframe remount flashes ## Stack - depends on #389 - followed by `fix: smooth scrubber end seeking` [result.mp4 <span class="graphite__hidden">(uploaded via Graphite)</span> <img class="graphite__hidden" src="https://app.graphite.com/user-attachments/thumbnails/ca71c177-5042-468d-906f-b353938f40f8.mp4" />](https://app.graphite.com/user-attachments/video/ca71c177-5042-468d-906f-b353938f40f8.mp4)
