Operator-delivered draft (S55) carried only brief_version/status/brief_quality/
research_topics and an explicit "reconcile frontmatter against brief-validator
before /trekplan" note. Add the required fields (type, task, slug,
research_status, phase_signals_partial) plus the brief_version 2.2 gates:
framing: refine (operator-confirmed — additive opt-in engine, swarm stays
default, no contract change) and a 5-line ## TL;DR. brief-validator passes
strict + --min-version 2.2. status stays draft pending operator review before
the /trekplan run.

Records the operator-supplied brief for an --engine {swarm|deep-research}
choice on /trekresearch's external phase (swarm stays default; deep-research
delegates the external phase to the built-in workflow with auto-fallback).
Backlog item only — not implemented. Lives beside the work (docs/), tracked.
