fix(cli): 1.30.2 — daemon service unit attaches to every joined mesh

claudemesh install was baking --mesh <primary> into the launchd plist /
systemd unit, locking the daemon to a single mesh and contradicting
1.26.0's multi-mesh design. users with >1 joined mesh fell off the
daemon path on every non-primary verb (cold-WS fallback, peer list
returning all meshes because the server-side filter ran against zero
attached state, "daemon spawn failed: socket did not appear" from
launched sessions in sibling meshes).

now: meshSlug is optional in InstallArgs; claudemesh install omits it
so the unit runs `claudemesh daemon up` with no flag, which attaches
to every joined mesh. `claudemesh daemon install-service --mesh <slug>`
is preserved as opt-in for single-mesh hosts and CI.
