Wire the KV-backed context/planning tools into the profile so the agent
uses them instead of relying on lossy conversation memory under compression.

- Workflow Plan: create a todo for non-trivial tasks.
- Workflow Test & verify: record the verification in the todo `validation`
  field when marking done (structural form of "never claim done without
  verification").
- Replace "Context drift recovery" with "Working state & memory":
  - todo: plan + verification tracking.
  - scratchpad: durable working memory across compression (sections
    goal/findings/errors/artifacts); read before final report.
  - Sub-agent handoff: write context to the scratchpad `context_transfer`
    section before spawn_agent — it is injected into the sub-agent
    automatically (the sub-agent does not inherit short-term memory).
  - schedule_recall: continue after the iteration limit, offload heavy
    work headlessly, poll builds/logs, chain multi-phase work.
  - reflect: selectively, before complex plans or when stuck (3 LLM calls).
  - memory: global cross-project facts, not a scratchpad/docs substitute.
  - Drift recovery folded into a closing paragraph aligned with the
    goal_anchoring machinery.

TUI visualization for schedule_recall is a follow-up task.
