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	Start one DSH child for this VS Code window (false = reuse only the configured user-managed endpoint); also starts at VS Code startup
`dsh.closePolicy`	`onVscodeExit`	When to stop the extension-owned server (see below)
`dsh.runtime.manifestUrl`	(empty)	HTTPS URL of a runtime release manifest (`schemaVersion: 1`, `artifacts` with embedded runtime manifests). Empty = use only the already installed verified runtime under VS Code global storage
`dsh.runtime.version`	(empty)	Optional DSH runtime version pin. Empty = installed current version, or the newest matching artifact when provisioning from 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.
