feat: Persist Studio manual edits via manifest (#593)

## Summary

Studio manual geometry edits now persist as a project-local manifest instead of being baked into composition source on each gesture.

The manifest lives at:

```text
.hyperframes/studio-manual-edits.json
```

It is the source of truth for manual drag, resize, rotation, inspector geometry edits, group moves, and selected-layer reset.

## Architecture

- **Manifest-backed edits**: each edit stores a kind (`path-offset`, `box-size`, `rotation`), a source-scoped target, and the edit values.
- **Source-scoped resolution**: targets include `sourceFile`, `id`, `selector`, and `selectorIndex`, so duplicate selectors in nested compositions resolve against the owning source file.
- **Additive CSS layer**: move uses CSS `translate`, resize writes stable dimensions/flex sizing, and rotation uses CSS `rotate` over the authored base.
- **Shared replay runtime**: Studio preview, thumbnails, frame capture, producer renders, and CLI Studio renders/thumbnails all use the same core manual-edit render script.
- **Animation-safe replay**: Studio reapplies the manual layer after load, refresh, timeline seeks, player operations, playback frames, thumbnail seeks, and render seeks instead of rewriting GSAP timelines.
- **History and handoff**: the manifest is a normal project file, so undo/redo and agent edits can preserve, modify, or remove manual visual edits explicitly.

## User Impact

Users can move, resize, rotate, group-move, and reset supported layers from the canvas or inspector, then refresh, capture thumbnails/screenshots, play animated compositions, and render videos without manual edits drifting away from the edited state.
