Add the ability to tag chats and use tags as filters in chat search

Feature request for product/service

Cursor IDE

Describe the request

It would be useful to have a tagging system for chats. Users could assign one or multiple custom tags to a chat, such as AWS, MongoDB, Work, Project X, or Learning.

These tags should then be usable as filters in search, making it easier to find and group chats related to the same topic or type of work.

For example, I could tag several chats with AWS and later search or filter by the AWS tag to quickly see all related conversations.

Ideally, tags would be manageable from the chat interface, and search could support filtering by one or multiple tags.
