 * Abort trigger detection for the Feishu/Lark channel plugin.

 * an abort/stop command *before* it enters the per-chat serial queue.
 *
 * The trigger word list and normalisation logic are copied from the
 * OpenClaw core (`src/auto-reply/reply/abort.ts`) so the plugin can
 * make a lightweight decision without importing the full reply pipeline.
 * The message still flows through `tryFastAbortFromMessage()` for
 * authoritative handling.
