The intake (prompter) agent was spawned with its role prompt missing, so it
only saw the gateway verbs layer (whose sole verb is `i_am_idle`) plus the
base rules. It concluded it had no way to act and refused to draft tasks —
the live intake chat produced empty turns and never called `propose_draft`.
Root cause: `prompter` was absent from `_ROLE_LAYER_MAP`, so `compose_prompt`
silently skipped `agents/prompts/roles/prompter.md` — the interviewer prompt
that defines the intake mission and the `propose_draft` tool. The tool was
wired into the SDK the whole time; the agent was just never told it existed.
Fix: map `prompter` to `prompter.md` so the role layer is composed in, the
same as every other role.
