* feat(slack): add thread.requireExplicitMention config option
When requireMention is true in a Slack channel, replying inside a thread
where the bot previously participated currently bypasses mention gating
via implicit mention detection. This makes the bot respond to every
thread message even without an explicit @mention.
Add channels.slack.thread.requireExplicitMention (default: false) which,
when set to true, suppresses implicit thread mentions. Only explicit
@bot mentions will trigger replies inside threads.
Closes#34389Closes#49972
* slack: refresh changelog and generated config artifacts
* slack: restore bundled channel metadata generation
