[Feature request] Custom relays

[Jasdemi]

In addition to following tags and instance relays, it would be nice to be able to create a customizable relay which includes various tags and/or instances. With options such as:

• filters (language, keyword, instances)
• private (can only be followed by select users) or public (anyone can follow)

Similar to Bluesky custom feeds.

This would help tremendously with content discoverability, especially for new users as you could share a curated relay with them . It would require an account management page to manage the custom relays.
