[feature]: Allow users to only see tasks/cards assigned to them

Is there an existing issue for this?

• I have searched the existing issues

Summary

Basically it would be nice option to have in Plane just like Teamhood where users with "collaborator(limited) access" can only see cards assigned to them or cads created by them only. While the admin an see all the tasks/cards on the board.

Why should this be worked on?

This would be good for assigning confidential leads to team members so they cannot see the leads of the other users and there are various other scenarios where it can be helpful, such as where teams are remote. And you are not ready to expose the entire tasks of a project to a remote team member or the one who recently joined.
