fix(discord): honor agent media roots in replies

CHANGELOG.md

@@ -14,6 +14,7 @@ Docs: https://docs.openclaw.ai
 
 - Docs/tool-loop detection config keys: align `docs/tools/loop-detection.md` examples and field names with the current `tools.loopDetection` schema to prevent copy-paste validation failures from outdated keys. (#33182) Thanks @Mylszd.
 - Discord/inbound debouncer: skip bot-own MESSAGE_CREATE events before they reach the debounce queue to avoid self-triggered slowdowns in busy servers. Thanks @thewilloftheshadow.
+- Discord/Agent-scoped media roots: pass `mediaLocalRoots` through Discord monitor reply delivery (message + component interaction paths) so local media attachments honor per-agent workspace roots instead of falling back to default global roots. Thanks @thewilloftheshadow.
 - Discord/presence defaults: send an online presence update on ready when no custom presence is configured so bots no longer appear offline by default. Thanks @thewilloftheshadow.
 - Discord/typing cleanup: stop typing indicators after silent/NO_REPLY runs by marking the run complete before dispatch idle cleanup. Thanks @thewilloftheshadow.
 - Discord/voice messages: request upload slots with JSON fetch calls so voice message uploads no longer fail with content-type errors. Thanks @thewilloftheshadow.
