/**
 * `bober evolve` — offline replay-gated prompt evolution.
 *
 * Reads the generator or evaluator agent prompt, proposes deterministic variants,
 * scores each ONLY via the Sprint 2 runReplayHarness gate (never live LLM runs),
 * keeps the Pareto frontier, and writes a promoted prompt under
 * .bober/evolve/<runId>/promoted/ ONLY when a variant beats the baseline with
 * zero regressions.
 *
 * SAFETY: this command NEVER writes under the live agent definitions directory.
 * All outputs are confined to .bober/evolve/<runId>/.
 *
 * Error handling: handler MUST NOT throw. Sets process.exitCode=1 and returns
 * on all errors. Pattern mirrors src/cli/commands/facts.ts and replay.ts.
