feat: unhide gateway and gateway-target CLI commands (#562)

Remove { hidden: true } from gateway and gateway-target Commander
subcommand registrations so they appear in `agentcore add --help`
and `agentcore remove --help`. Update AGENTS.md to reflect that
these primitives are no longer hidden/coming soon.

 Singletons are created in `registry.ts` and wired into CLI commands via `cli.ts`. See `src/cli/AGENTS.md` for details on
 adding new primitives.
