Desktop app crashes on startup when cached workspace directory is deleted #30750

Description

When a workspace directory is deleted from the filesystem, the desktop app fails to start properly because it tries to restore the non-existent workspace path.

Plugins

No response

OpenCode version

1.15.11

Steps to reproduce

Open a project folder in OpenCode desktop app (e.g., /Users/UserName/Documents/Projects/SomeProject)
Close the app
Delete that folder from Finder
Open OpenCode desktop app again
Expected Behavior:

App should detect the workspace no longer exists
Prompt user to select a new workspace or clean up the invalid entry
Start normally with a new/valid workspace
Actual Behavior:

App fails to subscribe to file watcher
MCP servers (e.g., codegraph) fail to start due to invalid cwd
Multiple errors in logs:
ERROR service=file.watcher dir=/Users/UserName/Documents/Projects/SomeProject cause=Error: No such file or directory
ERROR service=mcp key=codegraph cwd=/Users/UserName/Documents/Projects/SomeProject error=spawn codegraph ENOENT local mcp startup failed

Workaround:
Delete the cached workspace data manually:
rm -rf ~/Library/Application\ Support/ai.opencode.desktop/opencode.workspace.*.dat

Environment:
OpenCode version: 1.15.11
Platform: macOS arm64
Electron: 41.2.1
Additional Context:

The workspace path appears to be cached in the desktop app's Local Storage (LevelDB format), but there's no mechanism to validate if the path still exists before attempting to use it.
