fix(feishu): disable block streaming to prevent silent reply drops

xinhuagu · xinhuagu · commit b9350e0bc6d6 · 2026-03-07T00:26:57.000+01:00
When blockStreamingDefault is 'on' (the default), the block streaming pipeline calls feishu's deliver with kind 'block'. Feishu's deliver silently drops these chunks when renderMode is 'auto' and text has no code blocks/tables. The pipeline then marks didStream=true (no error was thrown), so the final reply is also suppressed — resulting in zero replies delivered. Set disableBlockStreaming: true in replyOptions so the agent bypasses the block streaming pipeline entirely for Feishu. Streaming cards via onPartialReply remain unaffected. Closes #38258
