🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add a mapped-but-missing-column case.

This case only tests a missing field mapping. It does not test a field with a configured column that is absent from table.columns.

Add a case with fields: { authorId: { column: 'author_id' } } and no author_id table column. Assert { name: 'author_id', nullable: true }. This detects regressions that replace the configured column name with the field name.

In `@packages/2-sql/1-core/contract/test/relation-storage.test.ts` at line 49, Add
a test case alongside the existing relation-storage fallback test for a field
configured with column “author_id” while table.columns omits that column; assert
the resolved result is name “author_id” with nullable true, preserving the
configured column name rather than falling back to the field name.
