fix(feishu): use msg_type media for mp4 video (fixes #33674) (#33720)

* fix(feishu): use msg_type media for mp4 video (fixes #33674)

* Feishu: harden streaming merge semantics and final reply dedupe

Use explicit streaming update semantics in the Feishu reply dispatcher:
treat onPartialReply payloads as snapshot updates and block fallback payloads
as delta chunks, then merge final text with the shared overlap-aware
mergeStreamingText helper before closing the stream.

Prevent duplicate final text delivery within the same dispatch cycle, and add
regression tests covering overlap snapshot merge, duplicate final suppression,
and block-as-delta behavior to guard against repeated/truncated output.

* fix(feishu): prefer message.reply for streaming cards in topic threads

* fix: reduce Feishu streaming card print_step to avoid duplicate rendering

Fixes openclaw/openclaw#33751

* Feishu: preserve media sends on duplicate finals and add media synthesis changelog

* Feishu: only dedupe exact duplicate final replies

* Feishu: use scoped plugin-sdk import in streaming-card tests
