Drop the enumeration of what the flag does not apply to, per operator
review on the sibling graceful-stop change. Regenerate the CLI doc so
the markdown-docs self-diff check stays in sync.
`hivectl restart [scope]` cycles the scoped containers — composes the
existing stop + start daemon ops client-side (reusing the merged Stop/Start
wire ops + global --socket), so no new wire/c0re surface. Same scope model
as stop/start (--agents/--agent/--ci/--forge/--gateway/--matrix), and
--graceful on the stop half. If the stop phase reports a failure the start
phase is skipped so a half-stopped hive isn't blindly started over.
Regenerated docs/tools/hivectl-cli.md.
The host admin socket path was duplicated on every daemon-assisted verb
(agents restart/restart-all, stop, start). Hoist it to a single global arg
on the top-level Cli (`--socket`, default DEFAULT_HOST_SOCKET, accepted
before or after the subcommand) and thread cli.socket through dispatch.
Verbs that don't talk to the daemon ignore it. Pure CLI-ergonomics change;
no wire/behaviour change. Regenerated docs/tools/hivectl-cli.md.
The hivectl-docs flake check regenerates docs/tools/hivectl-cli.md from the
clap command tree and asserts it's committed up to date. Adding the stop/start
verbs changed the CLI, so the doc was stale and the check failed. Regenerate it.
