✨ Allow stopping ws0 independently of other workspaces

Remove the guard in stop-devenv that refused to stop ws0 while any
ws1+ instance was running. Each workspace is now fully independent
and can be started/stopped in any order. Shared infra shuts down
only when no instances remain running.

Updated docs (devenv.md, agentic-devenv.md) and devenv memory to
reflect the new behavior.
