dsh web (0.1.0-rc.6 npm CLI) cannot boot on GitHub Actions ubuntu-latest: missing pty.node linux-x64 prebuild

[zoahdev]

Summary

dsh web from the published npm CLI (@deepseek-ai/dsh 0.1.0-rc.6) cannot boot on GitHub Actions ubuntu-latest. The loader fails while importing @deepseek-ai/dsh-subprocess-local:

Error: dsh: plugin tree failed to load: failed to apply loader entry include (cordis:include):
failed to import loader entry subprocess (@deepseek-ai/dsh-subprocess-local):
Failed to load native module: pty.node, checked: build/Release, build/Debug,
prebuilds/linux-x64: Error: Cannot find module './prebuilds/linux-x64//pty.node'

Reproduction

On any ubuntu-latest GitHub Actions runner (Node 24, pnpm 11):

export DSH_HOME="$(mktemp -d)/dsh-home"
pnpm dlx @deepseek-ai/dsh plugin --profile web add <any-dsh-plugin-tarball>
pnpm dlx @deepseek-ai/dsh web --port 4099

The web server never starts; the process exits with the error above. The same steps succeed on Windows (win32-x64 prebuild ships with the package).

Impact

• Community plugin CI cannot run a real dsh web boot smoke test on Linux runners.
• The plugin ecosystem's most common CI host (ubuntu-latest) is exactly where the native module is missing.

Suggested fix

Publish the linux-x64 prebuild for node-pty (or add a build step / fallback for the @deepseek-ai/dsh-subprocess-local package) in the 0.1.0-rc.x train. If a fix is already in progress, a note in the README would help plugin authors plan their CI.

Happy to provide more logs or test a candidate fix.
