The previous truthiness checks (, ) treated "" as falsy and converted it to None, which caused the field to be dropped from the message history entirely. Providers that require reasoning_content on all assistant messages then rejected subsequent requests. Replace truthiness checks with identity checks () so that empty-string reasoning_content is preserved as-is. The streaming path is unchanged since an empty join genuinely means no chunks received.

The shared split_message remains a plain-text chunker. The Telegram channel now uses _split_telegram_markdown for its raw Markdown paths that feed _markdown_to_telegram_html, preventing broken HTML rendering when splits fall inside fenced code blocks.

Subject: [PATCH 66/66] feat(slack): add groupRequireMention for allowlist
 channels

Slack's groupPolicy could either restrict to specific channels
("allowlist") or require an @mention ("mention"), but not both: in
allowlist mode the bot replied to every message in approved channels.

Add a groupRequireMention flag so that, when groupPolicy is "allowlist",
the bot only responds in channels listed in groupAllowFrom AND only when
@mentioned. Mirrors Signal's group.requireMention. No effect for the
"mention"/"open" policies, so existing configs are unchanged.

Extract the mention check into _is_mention and reuse it from both the
mention and allowlist branches.

 DM the bot directly or @mention it in a channel — it should respond!
