docs(agents): make code reviewers opt-in instead of automatic
Reviewer subagents cost several times more tokens than the implementation
itself, so running them after every task is not affordable. After an
implementation an agent now runs only the deterministic gate
(.agents/scripts/verify.sh); the checklists in .agents/review/ and the
reviewer-* subagents are launched only when explicitly requested.
