/**
 * Sink for the agent's operational log lines — subagent dispatch, warm-worker
 * fallback, lifeguard kills. These describe what the agent is doing to its own
 * machinery, not what the user asked for.
 *
 * They used to go straight to `console.error`. stdout is reserved for the JSON
 * event stream, so stderr looked free — but when the interactive TUI owns the
 * screen it is not. The TUI is a differential renderer: it tracks the frame it
 * painted (`previousLines`) and repositions by *relative* row deltas from its
 * own bookkeeping (`hardwareCursorRow`). A write it did not make scrolls the
 * terminal underneath it, and every later partial repaint lands one row off —
 * the visible result being duplicated rows (two `Agent [explore]` lines for one
 * dispatch) plus fragments of the log line wedged into the transcript, which
 * survive until something forces a full repaint. The TUI cannot defend itself
 * here; it has no way to learn that another writer touched the terminal. So the
 * writer has to hold back.
 *
 * Hence: silent while a TUI is attached, unchanged everywhere else (`--print`,
 * RPC, CI), where these lines are the only trace of a dispatch and where
 * `docs/routing.md`'s `[DISPATCH] … depth=2 …` check still has to work.
 *
 * Nothing is lost in the interactive case. A dispatch is already on screen as
 * the `Agent [explore]` tool row and its task-panel row, and every field of the
 * `[DISPATCH]` line is persisted to `dispatch-log.json`; warm-worker and
 * inherited-model fallbacks already surface as a `⚠` note on the task row.
 * Set `HOOCODE_DEBUG_AGENT_LOG=1` to tee the suppressed lines to
 * `~/.hoocode/agent/hoocode-debug.log` (mirrors HOOCODE_DEBUG_REDRAW).
