Run sqlc generate

error generating code: named param ListerID has incompatible types: sql.NullInt32, int32
Error: Process completed with exit code 1.

Thank you for the catch. The sqlc error arises because ListerID is used in two contexts with different nullability inference (int32 for user_roles vs sql.NullInt32 for grants), preventing a simple merge of the SQL parameters.

I have reverted the SQL change to keep lister_id and lister_match_id distinct to satisfy sqlc's strict type checking. However, I have updated the Go code in core/common/coredata.go to correctly pass the user's ID to lister_match_id (instead of potential incorrect values), ensuring the logic behaves as intended while keeping the query valid.

@jules what are our options for unification?

@jules what are our options for unification?

We have a few options to unify the parameters:

1. Duplicate Parameters (Reverted State): Keep lister_id and lister_match_id distinct in SQL to satisfy sqlc's type inference, but populate them with the same value in Go.
2. Force Nullability (narg): Use sqlc.narg(lister_id) in both places. This forces the generated Go parameter to be sql.NullInt32. This satisfies the nullable column comparison (g.user_id = ?) and works for the non-nullable column (ur.users_idusers = ?) because passing NULL to a non-nullable column check simply results in NULL (false), which is valid behavior for an unauthenticated user.

I have proceeded with Option 2 as it achieves the requested unification (ListerID is now the sole parameter) while maintaining type safety and correctness. I've updated the SQL, the generated code, and the usage in CoreData accordingly.
