Adam Moussa 22edd4143a feat(agent-team): P1/P2 graph wiring + coordinator daemon + run-team start/serve
build_graph gains injected live_plan_node/review_node/route_review: P1 = plan->END, P2 = clarify->plan->review->{build|loop-back|parked}. Coordinator composes clarifier->graph->ResumeWorker, wraps planner fail-safe, binds the GPT-4.1 review loop; run-team start/serve opt production into P2. Re-delivery uses a guarded CAS so a concurrently-answered row is never clobbered (closes RACE-REDELIVER).

"""Unit tests for the ``run-team.py`` operator CLI (design §3.3.1, §7.1 P1).
``run-team.py`` is a hyphenated entry script (per the design's "entry CLI
``run-team.py``"), so it cannot be imported by normal ``import`` syntax. These
tests load it via :mod:`importlib` from its file path and exercise the manual
ledger path against the FOUNDATION ``agent_team.db.schema`` ledger.
The tests assert the §3.3.1 manual-path contract: list open/parked questions,
answer-on-behalf / force-expire / supersede gated behind ``--confirm`` and
audit-logged, first-answer-wins semantics inherited from the foundation
compare-and-set, and read-only commands needing no confirmation.
