Slack: register typed channel/group message event handlers

CHANGELOG.md

@@ -72,6 +72,7 @@ Docs: https://docs.openclaw.ai
 - CLI/Cron: clarify `cron list` output by renaming `Agent` to `Agent ID` and adding a `Model` column for isolated agent-turn jobs. (#26259) Thanks @openperf.
 - Feishu/Reply media attachments: send Feishu reply `mediaUrl`/`mediaUrls` payloads as attachments alongside text/streamed replies in the reply dispatcher, including legacy fallback when `mediaUrls` is empty. (#28959) Thanks @icesword0760.
 - Slack/User-token resolution: normalize Slack account user-token sourcing through resolved account metadata (`SLACK_USER_TOKEN` env + config) so monitor reads, Slack actions, directory lookups, onboarding allow-from resolution, and capabilities probing consistently use the effective user token. (#28103) Thanks @Glucksberg.
+- Slack/Channel message subscriptions: register explicit `message.channels` and `message.groups` monitor handlers (alongside generic `message`) so channel/group event subscriptions are consumed even when Slack dispatches typed message event names. Fixes #31674.
 - Feishu/Outbound session routing: stop assuming bare `oc_` identifiers are always group chats, honor explicit `dm:`/`group:` prefixes for `oc_` chat IDs, and default ambiguous bare `oc_` targets to direct routing to avoid DM session misclassification. (#10407) Thanks @Bermudarat.
 - Feishu/Group session routing: add configurable group session scopes (`group`, `group_sender`, `group_topic`, `group_topic_sender`) with legacy `topicSessionMode=enabled` compatibility so Feishu group conversations can isolate sessions by sender/topic as configured. (#17798) Thanks @yfge.
 - Feishu/Reply-in-thread routing: add `replyInThread` config (`disabled|enabled`) for group replies, propagate `reply_in_thread` across text/card/media/streaming sends, and align topic-scoped session routing so newly created reply threads stay on the same session root. (#27325) Thanks @kcinzgg.
