Summary

Fixes openclaw#79409 - Feishu channel does not handle text slash commands (/compact, /new, /stop)

The Feishu channel was not setting CommandSource when dispatching messages, causing slash commands like /compact, /new, /stop to be treated as regular messages instead of being intercepted by the command handler.

Root Cause

In extensions/feishu/src/bot.ts, the buildCtxPayloadForAgent function was not setting CommandSource in the context payload. Other channels (Discord, Matrix, Tlon) all set CommandSource: "text" to indicate that the message is a text command.

Fix

Added detection of text commands (messages starting with /) and conditionally set CommandSource: "text" in the context payload, following the pattern used by other channels.

Verification

• Test that /compact command works in Feishu
• Test that /new command works in Feishu
• Test that /stop command works in Feishu
• Verify regular messages still work correctly

Changes

+    // Determine if this message is a text command (starts with /)
+    const isTextCommand = effectiveCommandProbeBody.trim().startsWith("/");
+
     // --- Shared context builder for dispatch ---
     ...
         CommandAuthorized: commandAuthorized,
+        ...(isTextCommand ? { CommandSource: "text" as const } : {}),
