Unify NostrUser and Author nodes; add migrations support
Some checks failed
Go / build-and-release (push) Has been cancelled
Details

Browse Source 
Merged 'Author' nodes into 'NostrUser' for unified identity tracking and social graph representation. Introduced migrations framework to handle schema changes, including retroactive updates for existing relationships and constraints. Updated tests, schema definitions, and documentation to reflect these changes.
