Add custom clj-kondo hooks for macroses to ensure that lint rules are followed inside them.

Macros to be handled:

• fx/defn - similarly to defn with check on metadata for ::events
• fx/merge - seems like it could be lint'ed as thread macro, plus warn on limitations
• defview
• letsubs - lint as let + check on types for

Found few cyclical dependencies in the source code.

Example:
features/announcements/index.js -> exports ANNOUNCEMENTS_ROUTES and also imports AnnouncementsStore from features/announcements/store.js

features/announcements/store.js -> imports ANNOUNCEMENTS_ROUTES from index.js resulting in cyclical dependency.

There are few more modules where the same issue is present.

It would be nice to have the ability to set the presence status to away when the screen is locked to have users of traditional clients not be confused by you being constantly available.
