Miguel Ángel 0cf03016b2 fix(engine): resolve external asset paths from compiled dir (#231) 
## Summary
- Parent-relative paths (e.g. `src="../file.wav"`) silently drop media from rendered MP4
- The compiler rewrites external paths to `hf-ext/` and copies files to the compiled directory, but both the audio mixer and video frame extractor only resolved against `projectDir` — never finding them
- Now checks `compiledDir` first (matching the file server's resolution order), then falls back to `projectDir`
- Fixes both `<audio>` and `<video>` elements with external paths

## Real-world context
Reported in Slack by Abhai — a TTS comparison video using `<audio src="../tts-voxcpm2.wav">` (audio file in parent directory, composition in subdirectory) rendered successfully but the output MP4 had no audio stream. The render completed without any error, silently dropping the audio.

## Testing

### Environment
- Linux (Ubuntu 20.04), ffmpeg 4.2
- Test composition: `subdir/index.html` with `<audio id="bg-audio" src="../test-audio.wav">`, WAV file at parent directory

### Before fix (main)
```
[AUDIO-DEBUG] element.src=hf-ext/tmp/hf-test-231/test-audio.wav
              baseDir=/tmp/hf-test-231/subdir
[AUDIO-DEBUG] resolved srcPath=/tmp/hf-test-231/subdir/hf-ext/tmp/hf-test-231/test-audio.wav
              exists=false
```

- Audio mixer tries `join(projectDir, "hf-ext/...")` → file doesn't exist at that path
- Output: **9.8 KB, video stream only** (confirmed via ffprobe)
- No error logged — audio silently dropped

### After fix (this branch)
```
[AUDIO-DEBUG] element.src=hf-ext/tmp/hf-test-231/test-audio.wav
              baseDir=/tmp/hf-test-231/subdir
              compiledDir=/tmp/.../compiled
[AUDIO-DEBUG] fromCompiled=/tmp/.../compiled/hf-ext/tmp/hf-test-231/test-audio.wav
              exists=true
[AUDIO-DEBUG] resolved srcPath=/tmp/.../compiled/hf-ext/tmp/hf-test-231/test-audio.wav
              exists=true
[AUDIO-RESULT] success=true, hasAudio=true
```

- Audio mixer checks `join(compiledDir, "hf-ext/...")` first → file found
- Output: **44.6 KB, video + audio streams** (confirmed via ffprobe)

### ffprobe comparison

| Branch | File size | Streams |
|--------|-----------|---------|
| `main` | 9.8 KB | `video (h264)` only |
| `fix` | 44.6 KB | `video (h264)` + `audio (aac)` |

### Path resolution flow
1. Compiler sees `<audio src="../test-audio.wav">`
2. Compiler resolves to absolute path, maps it to `hf-ext/tmp/.../test-audio.wav`
3. Compiler copies file to `compiled/hf-ext/tmp/.../test-audio.wav`
4. Audio mixer gets `element.src = "hf-ext/tmp/.../test-audio.wav"`
5. **main**: tries `join(projectDir, src)` → not found → silent drop
6. **fix**: tries `join(compiledDir, src)` first → found → audio mixed in

### Repro
```bash
mkdir -p /tmp/test/subdir
ffmpeg -f lavfi -i "sine=frequency=440:duration=2" /tmp/test/test-audio.wav -y
# Create subdir/index.html with <audio src="../test-audio.wav" ...>
cd /tmp/test/subdir && npx hyperframes render
ffprobe -v error -show_streams output.mp4  # video only on main, video+audio on fix
```

Miguel Ángel 110ea12597 fix(core,engine,producer): handle id-less media in sub-composition renders (#96) 
## What

Move the id-less media fix into the shared timing compiler so producer can resolve durations for sub-composition videos before inlining, then carry the merged result through engine parsing, regression coverage, and the regression Docker image used in CI.

This PR now does five concrete things:

- assigns stable ids to id-less media in core `compileTimingAttrs()` so unresolved duration injection can target them
- keeps the engine-side `parseVideoElements()` support for `video[src]` plus the newer `data-duration` / natural-duration fallback from `main`
- makes producer prefer sub-composition media metadata over the later inlined-document parse when the same media id appears in both places
- makes `sub-composition-video` a runnable regression test by fixing its metadata and checking in the missing `output/compiled.html` snapshot
- removes the stale `pnpm-workspace.yaml` copy step from `Dockerfile.test`, so regression CI builds the Bun-based test image from the current workspace layout

## Why

- media without an explicit `id` could not participate in unresolved-duration resolution early enough
- producer could lose the resolved sub-composition timing by overwriting it with the later inlined parse
- the regression fixture intended to cover this case was not actually running in CI because its `meta.json` was incomplete and the required compiled snapshot was missing
- the regression image definition still expected a deleted `pnpm-workspace.yaml`, so GitHub Actions failed before the test shard could start

Putting the id-generation step in core makes the behavior reusable instead of relying on producer-only HTML patching.

## How

### Shared compiler

- core `compileTimingAttrs()` now auto-assigns stable ids to id-less `video` / `audio` tags
- those generated ids are returned in `unresolved`, so `injectDurations()` can add `data-duration` and `data-end` to the same media element later in the pipeline
- added core tests that cover auto-id assignment and duration injection for generated ids

### Producer

- when producer combines `subVideos` / `subAudios` with the media re-parsed from the final inlined HTML, it now lets the sub-composition metadata win
- this preserves the resolved/clamped timing already computed for nested media instead of overwriting it with the later parse
- `sub-composition-video` now has valid regression metadata and a checked-in `output/compiled.html` snapshot so CI actually executes it

### Engine

- resolved the merge conflict in `videoFrameExtractor` by keeping the broader `video[src]` parsing from this branch and the `data-duration` / natural-duration fallback that landed on `main`
- added a focused engine unit test for videos without ids

### CI image

- `Dockerfile.test` now copies only `package.json` and `bun.lock` at the workspace root before `bun install --frozen-lockfile`
- this matches the current monorepo layout and removes the obsolete pnpm-era dependency on `pnpm-workspace.yaml`

## Test plan

- [x] `bun run --filter @hyperframes/core test`
- [x] `bun run --filter @hyperframes/engine test`
- [x] `bun run --filter @hyperframes/producer test --update --sequential sub-composition-video`
- [x] `bun run --filter @hyperframes/producer test --sequential sub-composition-video`
- [x] Browser check with `agent-browser` against the compiled fixture page (`http://127.0.0.1:8123/compiled.html`)
- [x] Clean tracked-only Docker build of `Dockerfile.test` with the PR version of the file applied

## Notes

- Latest regression workflow is green on `main`, but before this PR the `sub-composition-video` fixture was being skipped by the harness rather than exercised end to end.
- The CI Docker fix was validated from a tracked-only export to avoid local untracked worktree artifacts affecting the result.

Miguel Ángel 1230657ed0 fix(studio,runtime,engine,compiler): 8 bug fixes — audio, render, timeline, Lottie, thumbnails, video render (#133) 
## Summary

**Original 5 bugs fixed:**

- **Bug 1 — Audio silent after seek**: Added `Accept-Ranges` / `Content-Length` + `206 Partial Content` to the static asset server for byte-range seeking.
- **Bug 2 — Download 404 after restart**: Render list endpoint now registers on-disk renders into the in-memory job map.
- **Bug 3 — Timeline stops at GSAP end**: `resolveRootTimelineFromDocument` pads the GSAP timeline to match `data-duration` when the composition declares longer.
- **Bug 4 — Render stuck at 0%**: Store `jobState` reference (not spread copy) so async progress mutations reach the SSE stream.
- **Bug 5 — Lottie missing in preview/render**: Two fixes — (a) moved Lottie adapter before GSAP so `onUpdate` wins; (b) fixed bundler silently dropping external CDN `\<script src>` tags from sub-compositions (root cause: `$content(s).html()` returns `""` for external scripts).

**3 additional bugs fixed:**

- **Bug 6 — Blank thumbnails outside monorepo**: Implemented `generateThumbnail` in the CLI adapter using Puppeteer.
- **Bug 7 — Video empty in rendered sub-compositions**: Fixed `parseVideoElements` selector from `video[id][src]` to `video[src][data-start]` + auto-assign IDs.
- **Render errors**: Failed renders now show their error message in the renders panel.

- [x] Any project: render → progress advances past 0%, reaches 100%
- [x] Any project: complete render, restart `hyperframes dev`, Download → works
- [x] `intro-vid`: play → runs full 5s (not stopping at 3s)
- [x] `hyperframe-build-up-demo`: play → rocket Lottie visible during 0-2s ✅ verified
- [x] Outside monorepo: Compositions sidebar shows thumbnail images (not blank)
- [x] `bug.zip` project: render → video in polaroid sub-composition appears in output
- [x] Trigger a failed render → error message shown
