feat: new useMeeting subscription

[GuiLeme]

Describe the feature
We need to create a new custom hook subscription that works similarly to useMeeting, but with enhanced functionality. The hook should return all data that useMeeting provides while also accepting a projection function as an argument to allow consumers to transform the returned data.

Expected behavior
The new hook should:

1. Return all data from the useMeeting hook
2. Accept a projection function as an argument that transforms the returned data
3. Allow developers to efficiently select and transform only the data they need from the meeting context (without unecessary re-renders)

Additional context
This hook would provide a more efficient way to subscribe to meeting data with built-in projection/transformation capabilities, similar to selector patterns used in state management libraries.

Suggested hook names:

• useMeetingProjection;
• useProjectedMeeting;
• useMeetingData;
• useAllMeetingData;

I like useMeetingData and deprecate useMeeting.
