NVENC rejects the libx264 preset vocabulary (ultrafast / medium / slow /
...) with AVERROR(EINVAL) ("Error applying encoder options: Invalid
argument"), which surfaces as a bare `FFmpeg exited with code -22` from
spawn(). Because ENCODER_PRESETS passes these names straight through to
h264_nvenc / hevc_nvenc, every `--gpu` render using the `draft` tier
failed; `standard` (medium) and `high` (slow) only worked coincidentally
on ffmpeg builds that happened to accept those aliases. QSV has the same
problem on a narrower set (ultrafast / superfast / placebo).
Add `mapPresetForGpuEncoder` in utils/gpuEncoder.ts that translates the
libx264 vocabulary to each encoder's native names:
- nvenc: libx264 -> p1..p7 (already-native pN values pass through);
unknown values fall back to p4 (medium)
- qsv: ultrafast / superfast -> veryfast; placebo -> veryslow;
everything else passes through
- videotoolbox / vaapi / null: unchanged
Both buildEncoderArgs (chunkEncoder.ts) and buildStreamingArgs
(streamingEncoder.ts) now route through the helper before pushing
`-preset` to the ffmpeg arg vector.
To make the next encoder-options failure diagnosable without re-running
ffmpeg by hand, \`formatFfmpegError\` in utils/runFfmpeg.ts now appends
the last 15 non-empty stderr lines to the error string. The four call
sites that previously swallowed stderr (encodeFramesFromDir,
muxVideoWithAudio, applyFaststart, and the streaming encoder exit
handler) have been updated.
Tested end-to-end on an RTX 4080 with ffmpeg 8.1 NVENC across
\`--quality draft|standard|high\` plus \`--video-bitrate\` and \`--crf\`
overrides; the 6 renders were visually equivalent to the CPU baseline.

* feat: initial code port from hyperframes-internal
Port all OSS-ready packages from the internal monorepo:
- @hyperframes/core — shared types, HTML generation, GSAP utilities, runtime
- @hyperframes/cli — CLI for creating, previewing, and rendering compositions
- @hyperframes/engine — framework-agnostic rendering engine (BeginFrame + FFmpeg)
- @hyperframes/producer — video rendering pipeline (Puppeteer + FFmpeg)
- @hyperframes/ui-player — browser-based video player component
- @hyperframes/studio — composition editor (React frontend + Hono backend)
Includes regression test suite with Docker-based test harness.
All HeyGen-internal references, deployment infrastructure, and
proprietary assets have been removed. Package names migrated
from @app/* to @hyperframes/*.

- Replace sandbox-studio, sandbox-interceptor, __magicEditRuntime
with neutral names (studio, hyperframe-runtime, __hyperframeRuntime)
- Fix stale Vault API / localhost references in docs
- Remove broken deprecated_studio link

* fix: remove remaining internal codenames and stale references
- Delete stale producer README.md and PIPELINE.md (referenced nonexistent files)
- Replace "Cerberus" codename with "HyperFrames" in test design reviews
- Replace magic-edit postMessage identifiers with hf-preview/hf-parent
- Rename debug-magic-edit-timeline.ts to debug-timeline.ts
- Replace "Motion Cut" with "HyperFrames" in Timeline comments
- Fix studio/CLI references to nonexistent archive package
(use local data/projects/ dir, stub render proxy)
