Desktop profile crash: agent-loop missing sessionProjections after installing plugins

[SalamanaStt]

Caused by @linxin666/dsh-web-all

Summary

dsh-desktop 0.2.1-rc.3 (win32 x64, Electron 44.7.0) fails to boot with:
DesktopHostFatalError: startup failed: 1 required plugin did not activate

The required "agent-loop" plugin reports missing service "sessionProjections", and
33 plugins all wait on services (sessionProjections, fs, sandboxPolicy,
workingDirectory, etc.) — a deadlock at startup.

Root cause (reproduced on two machines)

The crash is triggered by installing the third-party bundle plugin
"@linxin666/dsh-web-all" into the desktop profile.

This package pulls in ~25 sub-modules (dsh-ssh, dsh-update, dsh-remote-bridge,
dsh-pet, and many client-ui-* packages). Once installed, the core
"session-projection-cache" plugin fails to activate, so nothing registers the
"sessionProjections" service, and every dependent plugin deadlocks.

Reproduction

1. Fresh dsh-desktop 0.2.1-rc.3 install → boots fine.
2. Add "@linxin666/dsh-web-all" to ~/.dsh/profiles/desktop/package.json dependencies.
3. Start desktop → immediate DesktopHostFatalError, 33 plugins waiting.
4. Fix: remove that dependency + move node_modules/@linxin666 out, OR delete
   ~/.dsh entirely → boots fine again.

What would help

1. The boot audit only says "1 required plugin did not activate" and lists the
   WAITING plugins, but never says which underlying plugin actually FAILED to import
   and why. It took manual digging through profiles to find it was
   session-projection-cache being blocked by the third-party bundle. Surfacing the
   real failing plugin + its error message would save hours.
2. Consider isolating third-party plugin load failures so a bad community plugin
   doesn't take down the entire required-plugin chain.
3. Note: the "web" profile boots fine with the same setup; only the "desktop"
   profile deadlocks.

Environment

• App: @deepseek-ai/dsh-desktop 0.2.1-rc.3
• Platform: win32 x64, Electron 44.7.0, Node 24.21.0

If can not find which plugin, try to delete .dsh under your user file.
