Move the supported systemd path to two services: an owner-user bangerd for
orchestration and a narrow root helper for bridge/tap, NAT/resolver, dm/loop,
and Firecracker ownership. This removes repeated sudo from daily vm and image
flows without leaving the general daemon running as root.
Add install metadata, system install/status/restart/uninstall commands, and a
system-owned runtime layout. Keep user SSH/config material in the owner home,
lock file_sync to the owner home, and move daemon known_hosts handling out of
the old root-owned control path.
Route privileged lifecycle steps through typed privilegedOps calls, harden the
two systemd units, and rewrite smoke plus docs around the supported service
model.
Verified with make build, make test, make lint, and make smoke on the
supported systemd host path.
CLI: introduce internal/cli.deps which owns every RPC/SSH/host-command
seam the tree used to reach through mutable package vars. Command
builders, orchestrators, and the completion helpers become methods on
*deps. Tests construct their own deps per case, so fakes no longer leak
across cases and tests are free to run in parallel.
Daemon: move workspaceInspectRepoFunc + workspaceImportFunc onto the
Daemon struct (workspaceInspectRepo / workspaceImport), mirroring the
existing guestWaitForSSH / guestDial pattern. Workspace-prepare tests
drop t.Parallel() guards now that they no longer mutate process-wide
state.
