refactor(maglevc): build the CLI on the golang-cli library

Browse Source 
Replace maglevc's hand-rolled command-tree CLI with
git.ipng.ch/ipng/golang-cli v1.3.0, mirroring the evpnc refactor. The
tree (commands.go) and the gRPC-status error unwrap (color.go) stay
app-specific; the generic parts — parse tree, completion, '?'-help, the
readline shell, one-shot dispatch, color helpers, and the watch keypress
handler — now come from the library.

- main.go: a single cli.App[grpcapi.MaglevClient] with a Connect
  callback; drops the flag/color-default/dispatch boilerplate.
- commands.go: `type node = cli.Node[grpcapi.MaglevClient]`; label() ->
  cli.Label(); dyn* gain the captured-args parameter the library's
  Dynamic signature carries; runQuit returns cli.ErrQuit.
- watch.go: keypress.WaitForKey replaces the inline cbreak helper.
- color.go: only formatError remains, reading cli.ColorEnabled().
- delete tree.go, complete.go, shell.go.
- tests use the library API; add TestTreeValid (cli.Validate).

Behavior is unchanged except labels/errors now use the library's bright
ANSI palette (was dark); escape lengths are identical so tabwriter
alignment is unaffected. maglevc additionally gains the OpenBSD readline
fix and BSD-correct watch keypress it previously lacked. Builds on linux
and openbsd.
