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

CHANGELOG.md

@@ -35,6 +35,7 @@ Docs: https://docs.openclaw.ai
 - Runtime/tool-state stability: recover from dangling Anthropic `tool_use` after compaction, serialize long-running Discord handler runs without blocking new inbound events, and prevent stale busy snapshots from suppressing stuck-channel recovery. (from #33630, #33583) Thanks @kevinWangSheng and @theotarr.
 - ACP/Discord startup hardening: clean up stuck ACP worker children on gateway restart, unbind stale ACP thread bindings during Discord startup reconciliation, and add per-thread listener watchdog timeouts so wedged turns cannot block later messages. (#33699) Thanks @dutifulbob.
 - Extensions/media local-root propagation: consistently forward `mediaLocalRoots` through extension `sendMedia` adapters (Google Chat, Slack, iMessage, Signal, WhatsApp), preserving non-local media behavior while restoring local attachment resolution from configured roots. Synthesis of #33581, #33545, #33540, #33536, #33528. Thanks @bmendonca3.
+- Feishu/video media send contract: keep mp4-like outbound payloads on `msg_type: "media"` (including reply and reply-in-thread paths) so videos render as media instead of degrading to file-link behavior, while preserving existing non-video file subtype handling. (from #33720, #33808, #33678) Thanks @polooooo, @dingjianrui, and @kevinWangSheng.
 - Gateway/security default response headers: add `Permissions-Policy: camera=(), microphone=(), geolocation=()` to baseline gateway HTTP security headers for all responses. (#30186) thanks @habakan.
 - Plugins/startup loading: lazily initialize plugin runtime, split startup-critical plugin SDK imports into `openclaw/plugin-sdk/core` and `openclaw/plugin-sdk/telegram`, and preserve `api.runtime` reflection semantics for plugin compatibility. (#28620) thanks @hmemcpy.
 - Plugins/startup performance: reduce bursty plugin discovery/manifest overhead with short in-process caches, skip importing bundled memory plugins that are disabled by slot selection, and speed legacy root `openclaw/plugin-sdk` compatibility via runtime root-alias routing while preserving backward compatibility. Thanks @gumadeiras.
