chat@4.35.0

Minor Changes

• 4cb7e5d: Add a chat/workflow subpath with requestApproval(): durable human-in-the-loop approvals built on Workflow SDK. It posts an approval card with Approve/Deny buttons, suspends the workflow until a user decides (or an optional timeout elapses), validates approvers, finalizes the card with the outcome, and returns { approved, timedOut, user }. Also exports the buildApprovalCard and buildResolvedCard builders. Requires the new optional workflow peer dependency.
• 46681f5: Expose Microsoft Graph email addresses on normalized incoming Teams message authors. Resolved user profiles are cached in the state adapter (1 hour, failed lookups 5 minutes) so the lookup doesn't add a Graph call per message.

Patch Changes

• 80def3a: Add optional isSystem field to the normalized message Author type to distinguish platform-generated messages from humans and bots. The Slack adapter now sets isSystem: true for messages authored by Slack's reserved USLACK user (e.g. "@user archived the channel" notifications in DMs), so consumers no longer need to hard-code Slack-specific user IDs.

• 93a58af: Show explicitly configured progress as a native Teams DM status while preserving native streaming.

• 25f3099: toAiMessages no longer drops messages that have no text. A message with an empty text body is now kept when it has links or attachments the converter can include: images and text files (text/*, JSON, XML, YAML, etc.) with a working fetchData(). Messages whose only attachments are unsupported (video, audio, other file types, or attachments without fetchData()) are still skipped, and onUnsupportedAttachment now fires for video/audio attachments on these previously filtered messages.

  Note: multipart content no longer always starts with a text part. When a kept message had no text, its content array contains only attachment parts.
