Richard R 3d5dfd2a88 refactor(compute-worker): migrate compute logic to modular architecture
- Remove legacy compute-worker monolith under `src/compute/`, including PDF and Whisper inference, control-plane, and runtime orchestration
- Move PDF and Whisper inference logic to new `src/inference/` module
- Move control-plane, orchestrator, and state machine logic to `src/operations/`
- Move NATS/JetStream adapters to `src/infrastructure/`
- Move job orchestration, progress, and artifact persistence to `src/jobs/`
- Update imports throughout tests and main app to reference new module structure
- Update Dockerfile and scripts to use new asset paths
- Add new entrypoints: `src/api/app.ts` and `src/api/contracts.ts`
- Remove obsolete files and update `.gitignore` for new dev artifacts

This refactor modularizes the compute-worker, improving maintainability and separation of concerns. No functional changes to inference or orchestration logic.

BREAKING CHANGE: compute-worker internal APIs, directory structure, and imports have changed; downstream code must update imports and integration points.
