Pull request overview

This PR adds first-class support for Teams “feedback loop” configuration, including a new feedbackLoop channelData shape (default vs custom) and the associated message/fetchTask invoke path needed for custom feedback task modules.

Changes:

• Introduces ChannelData.feedbackLoop (and FeedbackLoop model) while keeping feedbackLoopEnabled as a legacy alias.
• Adds normalization logic in Activity.withChannelData() and extends Activity.addFeedback() to support 'default' | 'custom' modes, with updated tests.
• Adds routing/type support for the message/fetchTask invoke (aliases + response typing) and updates devtools’ feedback detection.

[lilyydu]

you're probably thinking of this one -

teams.ts/packages/api/src/activities/invoke/message/submit-action.ts

Line 26 in 0a7ce39

reaction: 'like' | 'dislike';

but different invoke activity (this is for default)
