With dsh.autoStart on, the server is started at VS Code startup even if the sidebar is never opened

Configuration

Key	Default	Description
`dsh.port`	3080	Port to probe/start the DSH web server on
`dsh.host`	127.0.0.1	Fixed loopback bind required by the current DSH Web profile
`dsh.autoStart`	true	At VS Code startup, launch the official DSH with the selected home and `web` profile; reuse the configured endpoint if runtime resolution fails (false = reuse only)
`dsh.home.mode`	`shared`	`shared` uses the official DSH home; `isolated` uses extension-private `globalStorage/.dsh` and a separate module configuration
`dsh.home.path`	(empty)	Machine-scoped absolute override for shared mode; empty follows `DSH_HOME`, then `~/.dsh`
`dsh.closePolicy`	`onVscodeExit`	When to stop the extension-owned server (see below)
`dsh.local.packageRoot`	(empty)	Optional absolute official `@deepseek-ai/dsh` package root; empty auto-detects the global npm installation
`dsh.local.nodePath`	(empty)	Optional absolute Node.js executable path; empty auto-detects it
`dsh.runtime.manifestUrl`	(empty)	Optional HTTPS runtime release manifest; empty uses the local official npm DSH, non-empty opts into manifest/SHA-256-verified managed-runtime provisioning
`dsh.runtime.version`	(empty)	Optional managed-runtime version pin; only applies with a manifest URL

dsh.closePolicy values:

Value	Behavior
`onVscodeExit`	Stop the owned server only when VS Code exits (default)
`onViewClose`	Also stop the owned server when the sidebar view is closed
`never`	Never stop automatically — use the Stop DSH Server command

A reused (non-owned) instance is never stopped by any policy or command.
