## Summary PR 3 of 5 in the hf#732 decomposition stack. Adds a `worker_threads`-based pool that runs the shader-transition blend (one of 15 transition shaders) on a fixed-size worker pool. **No production wiring yet** — the pool stands alone; PR 4 wires it. The shader blend is a hot inner loop over every pixel of every transition frame at 16bpc. Moving it off the main event loop removes the JS-event-loop ceiling that capped throughput in earlier hf#732 iterations. ### New files - `packages/producer/src/services/shaderTransitionWorker.ts` — worker entry. Imports from `@hyperframes/engine/shader-transitions` (zero-import TS source). - `packages/producer/src/services/shaderTransitionWorkerPool.ts` — fixed-size pool. Uses `transferList` so the 16bpc HDR `from`/`to`/`out` buffers move by ownership. - `packages/producer/src/services/shaderTransitionWorkerPool.test.ts` — 6 vitest tests pinning byte-equivalence across all 15 shaders, transferList correctness, pool lifecycle. All pass. ### Build wiring - `packages/cli/tsup.config.ts`: third tsup entry emits `dist/shaderTransitionWorker.js`. - `packages/producer/build.mjs`: fourth esbuild entry for direct producer consumers. - `packages/engine/package.json`: adds `./shader-transitions` subpath export. ## Stack Stacked on top of #757 (PR 2: pngDecodeBlit pool). No behavior change in any render. ## Test plan - [x] 6 pool tests pass - [x] Producer + engine typecheck clean - [x] oxlint clean — Vai
