Adds three small but high-leverage presentation tweaks for v0.1:
1. internal/cli/style is a new ~70 LOC package with Pass/Fail/Warn/
Dim/Bold helpers. Each is TTY-gated and obeys NO_COLOR. No
external dep. Wired into the doctor PASS/FAIL/WARN status, the
"banger:" error prefix on stderr, and the dim 'ready in <elapsed>'
line.
2. internal/cli/errors translates rpc.ErrorResponse into user-facing
text. operation_failed becomes invisible (the message wins);
not_found, already_exists, bad_request, bad_version, unauthorized,
unknown_method get short labels; unknown codes pass through. The
daemon-attached op_id lands in dim parens — paste into
journalctl --grep to find the daemon log line that produced the
failure.
3. Tabwriter config converges on (0, 8, 2, ' ', 0) across every
list/table command. The vm prune confirmation table picked up the
right config; system install + system status switched from bare
"key: value\n" lines to tabular form. printVMSpecLine drops its
Unicode middle dot for an ASCII '|' so terminals without UTF-8
render cleanly.
Tests cover translateRPCError for every code, style helpers no-op
on non-TTY and under NO_COLOR. Smoke status greps switch from
"key: value" to "key value" to match the new format.

systemd's Type=simple reports a unit "active" the moment its
ExecStart binary is exec()'d, which for bangerd happens well before
the daemon has read its config and bound /run/banger/bangerd.sock.
'banger system install' and 'banger system restart' both returned
inside that window, so the very next 'banger ...' command would hit
ensureDaemon, miss on a single ping, and exit with "service not
reachable; run sudo banger system restart" — the same restart that
had just succeeded. Smoke tripped over this on every run.
Add waitForDaemonReady: poll daemonPing for up to 15s after the
restart returns. Both the system install and restart paths now
block until the daemon is genuinely accepting RPCs, so the next
CLI invocation can talk to it without retrying.

Frontier models tend to discover a CLI by running --help, scanning
the Long description, and inferring the dominant workflow from the
examples. Today's banger help reads like a man page index — every
verb has a one-line Short and nothing else. This rewrites the
groups (banger, vm, vm workspace, image, kernel, system,
ssh-config) so each landing page answers "what is this for, what's
the 80% command, what comes next" in three to ten lines, with
runnable examples.
Also disambiguates the near-twin lifecycle commands so a model
reading the subcommand index can tell stop/kill/delete apart at a
glance:
start Start a stopped VM
stop Stop a running VM gracefully
restart Stop then start a VM
kill Force-kill a VM (use when 'vm stop' hangs)
delete Stop a VM and remove its disks (irreversible)
vm create / vm ssh / vm logs / vm show pick up Long descriptions
and examples for the same reason. No behaviour changes; help text
only.

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.
