fix: correct typos in comments and proto annotations

Fix spelling mistakes in Go code comments and a proto comment:

- prepand -> prepend (internal/codegen/golang/struct.go)
- unsiged -> unsigned (internal/codegen/golang/opts/override.go)
- desination -> destination (internal/tools/sqlc-pg-gen/main.go)
- implmented -> implemented (internal/tools/sqlc-pg-gen/proc.go)
- Overides -> Overrides (protos/plugin/codegen.proto)

All changes are in comments only — no logic or behavior is affected.
