docs(cli): daemon coverage in --help, daemon usage block, SKILL.md

- Root --help now lists the daemon subcommand suite (was missing).
- claudemesh daemon (no subcommand) prints a usage block instead of
  silently launching the foreground daemon. Adds help|--help|-h aliases.
- SKILL.md gains a "Daemon path (v0.9.0, opt-in, fastest)" section
  explaining the runtime, lifecycle, and that it's independent from
  claudemesh install.

Released as 1.22.1 on npm.
