Say what each verb replaces, so the agent is pointed at it instead of a shell command (hq ADR 0245)

A seat's verb names the shell commands it is the mesh's way to do, and a module says it for its own
tools in its manifest; the tools verb and module list --json carry both, for the mesh MCP server's
search, the agent's instructions and the guard on its shell.
