Richard R f1aa1c3e3b feat(compute): add external compute worker backend and integration
Introduce support for external compute worker mode (`COMPUTE_MODE=worker`) using a new `WorkerComputeBackend`. This enables offloading heavy ONNX Whisper alignment and PDF layout parsing to a standalone worker service (Redis + BullMQ), improving scalability and compatibility with serverless/limited environments.

- Add `@openreader/compute-core` as a shared package for ONNX inference and PDF parsing logic.
- Implement `WorkerComputeBackend` and worker contract/types for remote job execution.
- Update compute backend selection logic and remove previous worker mode guards.
- Extend `WhisperAlignInput` and `PdfLayoutInput` types to support object keys for remote data access.
- Refactor local compute backend to use `@openreader/compute-core` and support both buffer and object key inputs.
- Update job runner, TTS segment alignment, and PDF layout parsing flows to use new compute backend APIs.
- Add scripts, Docker workflow, and documentation for deploying and running the compute worker.
- Update environment variable docs and examples for worker mode, including storage requirements and configuration.
- Document published images and stack changes to reflect the new compute worker architecture.

BREAKING CHANGE: `COMPUTE_MODE=worker` now requires an external compute worker service and S3-compatible object storage. Embedded SeaweedFS (`weed mini`) is not supported in worker mode. See the new documentation for deployment and configuration details.

:::warning SeaweedFS Compatibility Note (April 16, 2026)
If you see intermittent S3 `InternalError` upload failures with embedded storage, use SeaweedFS `4.18`.
OpenReader currently pins `4.18` in CI and Docker builds while `4.19` compatibility is investigated.

<summary><strong>Word-by-word highlighting (optional)</strong></summary>
No extra native Whisper CLI build step is required.
Set `COMPUTE_MODE=local` to enable built-in ONNX word alignment in-process.
If you need mirrors or pinned artifact locations, set `WHISPER_MODEL_BASE_URL` in `.env`.
</details>
<details>
<summary><strong>External compute worker dev stack (optional)</strong></summary>
Use this when you want durable compute with Redis/BullMQ while keeping Next.js on native host `pnpm dev`.
Full worker deployment details are in [Compute Worker (Redis + BullMQ)](./compute-worker).
Start only Redis + compute-worker via compose watch:
```bash
docker compose --env-file compute/worker/.env -f compute/worker/docker-compose.yml up --watch
# or: pnpm compute:dev:watch
```
`compute/worker/.env.example` contains a starter config. Copy it to `compute/worker/.env` and adjust values for your environment.
Run the main app separately on the host:
```bash
pnpm dev
```
For app server worker mode, set:
```env
COMPUTE_MODE=worker
COMPUTE_WORKER_URL=http://localhost:8081
COMPUTE_WORKER_TOKEN=<same-token-used-by-worker>
```
Worker mode requires worker-reachable shared object storage (S3-compatible endpoint).
Non-exposed embedded `weed mini` is not a supported topology for external worker mode.

## Steps
### Required flow
1. Clone the repository.
```bash
git clone https://github.com/richardr1126/openreader.git
cd openreader
```
2. Install dependencies.
```bash
pnpm i
```
3. Configure the environment.
```bash
cp .env.example .env
```
Then edit `.env`.
Use one of these `.env` mode templates:
<Tabs groupId="local-env-modes">
<TabItem value="no-auth" label="No Auth (simple)" default>
```env
API_BASE=http://host.docker.internal:8880/v1
API_KEY=none
COMPUTE_MODE=local
# Leave BASE_URL and AUTH_SECRET unset to keep auth disabled.
# (Admin panel is unavailable without auth.)
# API_BASE/API_KEY seed a shared default provider if you want shared mode.
```
</TabItem>
<TabItem value="auth-enabled" label="Auth Enabled">
```env
API_BASE=http://host.docker.internal:8880/v1
API_KEY=none
COMPUTE_MODE=local
BASE_URL=http://localhost:3003
AUTH_SECRET=<generate-with-openssl-rand-hex-32>
# Optional when you need multiple local origins:
# AUTH_TRUSTED_ORIGINS=http://localhost:3003,http://127.0.0.1:3003
```
</TabItem>
<TabItem value="auth-with-admin" label="Auth + Admin Panel">
```env
# API_BASE / API_KEY are seeded into the admin "default-openai" shared provider
# on first boot, then no longer read. Manage them in Settings → Admin afterwards.
API_BASE=http://host.docker.internal:8880/v1
API_KEY=none
COMPUTE_MODE=local
BASE_URL=http://localhost:3003
AUTH_SECRET=<generate-with-openssl-rand-hex-32>
# Comma-separated emails to auto-promote to admin on signin.
ADMIN_EMAILS=you@example.com
```
</TabItem>
<TabItem value="external-s3" label="External S3">
```env

API_KEY=none
COMPUTE_MODE=local
USE_EMBEDDED_WEED_MINI=false

:::note Env vars vs. admin panel
On first boot, `API_KEY` / `API_BASE` and any `RUNTIME_SEED_*` flags you've set get auto-seeded into the admin-managed runtime config (DB-backed, keys encrypted at rest). After that, the admin UI is authoritative and editing those env vars no longer changes app behavior. See [Admin Panel](../configure/admin-panel).
:::
:::note User BYOK restriction default
If you want each user to enter personal provider credentials, set `restrictUserApiKeys=false` (from **Settings → Admin** when auth/admin is enabled, or via legacy first-boot seed `RUNTIME_SEED_RESTRICT_USER_API_KEYS=false` for no-admin bootstrap flows).
:::
:::info
For all environment variables, see [Environment Variables](../reference/environment-variables).
:::
See [Auth](../configure/auth) for app/auth behavior.
See [Admin Panel](../configure/admin-panel) for the shared-provider and feature-flag management UI.
Storage configuration details are in [Object / Blob Storage](../configure/object-blob-storage).
Refer to [Database](../configure/database) for database modes.
Learn about migration behavior and commands in [Migrations](../configure/migrations).
4. Start the app.
<Tabs groupId="local-run-mode">
<TabItem value="dev" label="Dev (recommended)" default>
```bash
pnpm dev
```
</TabItem>
<TabItem value="prod" label="Build + Start">
```bash
pnpm build
pnpm start

</TabItem>
</Tabs>
:::warning API Base Reachability
`API_BASE` must be reachable from the Next.js server process, not just your browser.
:::
Visit [http://localhost:3003](http://localhost:3003).
### Optional workflows
Run manual DB migrations only for troubleshooting or explicit migration workflows:
- Migrations run automatically on startup through the shared entrypoint for both `pnpm dev` and `pnpm start`.
```bash
pnpm migrate
```
:::info
If `POSTGRES_URL` is set, migrations target Postgres; otherwise local SQLite is used. To disable automatic startup migrations, set `RUN_DRIZZLE_MIGRATIONS=false` and/or `RUN_FS_MIGRATIONS=false`. You can run storage migration manually with `pnpm migrate-fs`.
