fix(webapp): make SDK bundle-docs build step work in pruned Docker image

[d-cs]

Summary

The webapp Docker image build runs pnpm run build --filter=webapp..., which builds @trigger.dev/sdk as a dependency. The SDK's build script recently gained a bundle-docs step (tsx ../../scripts/bundleSdkDocs.ts), but the build couldn't run it in the pruned image, breaking the image build.

Two things were missing:

• docker/Dockerfile copied scripts/updateVersion.ts into the builder stage but not scripts/bundleSdkDocs.ts, so the step failed with ERR_MODULE_NOT_FOUND.
• Even with the script present, the repo-level docs/ tree it reads is a separate workspace package that isn't in webapp's dependency graph, so turbo prune --scope=webapp excludes it — the script's missing-docs guard would then fail the build.

Design

The Dockerfile now copies bundleSdkDocs.ts alongside updateVersion.ts. bundleSdkDocs.ts skips gracefully when the repo docs/ tree is absent, which is exactly the pruned-dependency-build case (the SDK is compiled there but never published). Publishing always runs from the full monorepo where docs/ exists, so the missing-docs guard still protects releases — it only fires when docs/ is present but a cited doc is genuinely missing, rather than when the whole tree was pruned away. This avoids dragging 27M of docs into a throwaway builder stage.

Test plan

• bundle-docs from the full monorepo still bundles all cited docs (exit 0)
• Simulated pruned tree without docs/ skips cleanly instead of failing
• Webapp Docker image build succeeds in CI

Walkthrough

scripts/bundleSdkDocs.ts gains an early-exit path: at the start of bundleSdkDocs(), it uses fs.access to check whether the repo-level docs/ directory exists. If the directory is absent, it logs a skip message and returns without executing the manifest collection or bundling logic. docker/Dockerfile adds a COPY instruction in the builder stage to copy scripts/bundleSdkDocs.ts into the container, making it available for the subsequent pnpm run generate and build steps.
