First v0.3.x release on the Phase 0 cross-platform CI baseline.
## Cross-platform bug fixes (375ea4e)
User-reported bugs from a Pinokio/Windows session:
- Docker `compose --profile gpu up` no longer port-conflicts on 3900 — restored `profiles: ["cpu"]` that #49 wrongly reverted on CodeRabbit's advice.
- Argos / pip install from the UI now works inside Docker — added `_in_virtualenv()` runtime check; `run_pip` injects `--system` automatically when on system Python.
- Speaker diarization warning toast — when pyannote silently falls back to the silence-gap heuristic (missing HF_TOKEN, license not accepted, network blocked), `_diarize()` now returns `(segments, warning)`; `useDubWorkflow` renders an 8-second toast.
## Dub editor UX (d5df454)
Six fixes per annotated screenshots:
- Editable segment start times (`m:ss.s` or raw seconds; Esc reverts, Enter commits; rejects overlap with end).
- Click a transcript row → seek the waveform/video (`WaveformTimeline` now forwardRef's `seekTo(time)`).
- Speaker is datalist-backed (pulls from detected speaker clones; free text still allowed).
- Scissors menu splits at cursor — uses live caret, then last caret, then sentence-boundary fallback.
- Mouse-wheel scrolls the waveform; Cmd/Ctrl left alone for browser pinch-zoom.
- Menu popover collision: added `avoidCollisions` + `collisionPadding=8` to Radix Content; removed `position: fixed` from `.ui-menu`.
## VRAM-aware GPU pool (73dbe18)
`_gpu_pool` was hardcoded `ThreadPoolExecutor(max_workers=1)` since introduction — every TTS forward serialized through one thread.
- CUDA / ROCm: `workers = clamp(1, free_GB // 2.5, 4)`. 16 GB card with ~14 GB free → 4 workers → ~4× throughput on multi-segment dubs.
- MPS / CPU / unknown: 1 worker.
- `OMNIVOICE_GPU_WORKERS` env var override (clamped 1..16).
- Module `__getattr__` preserves the public `_gpu_pool` symbol for existing callers.
## Stories tab — wire-up + UX (f6bbc7a)
The 264-line `StoriesEditor` component existed but was mounted nowhere. Now wired into NavRail + lazy-loaded on `mode === 'stories'`. Added Paste & Split panel (sentence-boundary chunking) and per-track `[pause 0.5s]` insertion.
## Stories — pauses + inline voice (edd3a1d)
`frontend/src/utils/storyTokens.js` — tokenizer for `[pause X.Ys]` and `[voice:X]…[voice:default]` markers. Voice switches are stateful (carry forward). 13 new vitest cases (vitest now 24/24).
## Verified
- 214 backend tests pass (3 skipped, 10 xfailed, 3 xpassed)
- 23 router-smoke tests pass
- 24/24 vitest cases pass (13 new)
- All 7 Phase 0 CI checks green (Tauri shell + Smoke on macOS/Windows/Linux + Tests)
