feat(cli): gate standalone resource command families

-  `agentcore harness` — this is how the TUI launches).

 - **Leaf nodes** (built with `createHandler(...)`) do the work. They declare
   their own flags/arguments (validated and coerced via zod schemas) and receive
   a typed object in `handle(ctx, flags, args)`.

 Use `--help` for subcommands and flags, or browse the [command reference](command.md):
 
 ```bash
 agentcore --help
 agentcore add --help
-agentcore runtime invoke --help
+agentcore invoke --help
 ```
 
 Supported bare commands open their interactive flows in a terminal. Operation
-flags select headless behavior for most commands, but invoke commands can use
-selectors such as `--id` and `--session-id` to seed an interactive console.
+flags select headless behavior for most commands. Project invoke commands can
+use `--name` and `--target` to select a deployed agent for an interactive session.
 Run `agentcore create` for guided setup. To create a default project without
 the wizard, run `agentcore create --name MyAssistant`.
