Implement pinned (sticky) header and footer #80

Open heoblitz opened 1 month ago

heoblitz commented 1 month ago

What is this PR for?

This PR introduces support for pinned (sticky) headers and footers. The implementation allows headers and footers to stay visible within the collection view's bounds.

The changes will not impact existing ChatLayout users who do not utilize the pinned feature.
