fix(replies): preserve rich coalesced block replies (#81689)

CHANGELOG.md

@@ -48,6 +48,7 @@ Docs: https://docs.openclaw.ai
 - Codex startup: treat selectable configured OpenAI agent models as Codex runtime requirements during plugin auto-enable, startup planning, and doctor install repair, so Anthropic-primary configs can still switch to OpenAI/Codex cleanly.
 - Agents: preserve source-reply delivery metadata when merging tool-returned media into the final reply, keeping message-tool-only replies deliverable and mirrored. Thanks @pashpashpash and @vincentkoc.
 - Replies: treat rich presentation, interactive controls, and channel-native payload data as outbound content across follow-up, heartbeat, cron, ACP, and block-streaming delivery paths, preventing card/button-only replies from being dropped as empty.
+- Replies: deliver rich-only block replies even when block-streaming coalescing is enabled, keeping card and button payloads from being dropped by the text coalescer. Thanks @pashpashpash.
 - macOS/companion: require system TLS trust before pinning a first-use direct `wss://` gateway certificate and honor `gateway.remote.tlsFingerprint` as the explicit pin for remote node-mode sessions, so fresh endpoints fail closed when macOS cannot trust the certificate unless configured out of band. Fixes #50642. Thanks @BunsDev.
 - Update: snapshot config before update-time repair and restart writes, preserve plugin install records through doctor cleanup, and keep update-time config size drops from blocking the update while pointing users to the pre-update backup. Fixes #80077. (#80257) Thanks @Jerry-Xin and @vincentkoc.
 - WebChat/TUI: route Codex `tools.message` source replies to the active internal UI turn and mirror them to session history, so message-tool-only harness replies, including rich presentation and button-only replies, no longer disappear while WebChat and TUI remain non-targetable outbound channels. (#81586) Thanks @pashpashpash.
