feat: include only dsh-context in agent VM setup

Browse Source 
Install through the upstream CLI before Web startup, preserve existing profile state and skip completed installs. Keep pnpm's SQLite store on the guest cache disk and map the caller to namespace root for 9p atomic saves, without host-root privileges.

Cover context-only installation, retries, idempotence and preservation with offline checks. Validate real VM boot, ports, Firefox and a live DSH/context launch using a disposable profile.
