"""Add tasks.board_review_complete — the board-review handoff flag.

A board/coordination task (no repo of its own, carries a product) is reviewed
by BOTH the Product Owner and the Head of Marketing before the CEO hands it to
Main PM. The task stays ``pending`` throughout — that pending state is what
drives Main PM dispatch once the CEO approves. The CEO's Approve & Start button
must NOT appear until the board has actually finished reviewing, so we persist a
flag the orchestrator sets once both reviewers are done. Defaults to False;
existing rows backfill to False (no board task has been reviewed retroactively).
