/**
 * The watch daemon's log — readable by a human by default, JSON when a machine
 * is going to read it.
 *
 * ── Why this is not just `createLogger()` ────────────────────────────────
 * The engine's logger emits JSON to stdout, which is right for a server pod whose
 * output goes to Loki. This daemon's output goes somewhere different: a file on
 * the user's own laptop that THEY tail, that `chat-recall doctor` points them at,
 * and that is the first thing anyone reads when their sync looks wrong. And
 * `pino-pretty` is not a dependency of this package — the native-free guard keeps
 * the collector's dependency list minimal — so LOG_PRETTY silently falls back to
 * JSON here.
 *
 * Converting 48 `console.*` calls to JSON would therefore have made the one
 * surface a user actually reads unreadable, in exchange for structure nothing was
 * consuming. So: human-readable lines by default, identical in shape to what the
 * daemon has always printed, and `CHAT_RECALL_LOG_JSON=1` for an operator
 * shipping to Loki or Vector.
 *
 * ── What this buys over console.* ────────────────────────────────────────
 *   LEVELS      `CHAT_RECALL_LOG_LEVEL=warn` silences the routine chatter. There
 *               was no way to turn down a daemon that logs a heartbeat a minute.
 *   STRUCTURE   fields travel alongside the message, so the JSON mode is
 *               genuinely parseable rather than a string to regex.
 *   ONE PLACE   the timestamp format, the level filter and the destination are
 *               decided once instead of at 48 call sites.
