Tool availability is a strict per-stage allowlist, so the task doctrine was
inert in role_pipeline — no stage granted the tools. Add them where they fit
each stage's tier and role, and point the stage prompts at the lifecycle:
- analyst (read-only): task_search/task_context to find related or duplicate
work and ground the analysis.
- implementer: full set — claim before working, submit_for_review once
verification passes, create one if the work warrants tracking.
- reviewer: task_context to judge against the task's own criteria, task_update
to complete it on an approved verdict.

Replace the inline "Q:"-prefixed-summary convention with a structured
`questions` array of {prompt, options?, multiSelect?, header?} objects that
rides in the analysis artifact (allowed by additionalProperties:true, skipped
by JsonSchemaValidator). The kernel parses it to drive the producer-exit
clarification loop; the TUI renders it as an interactive form.
