Extend SchemaCache TableColumn with not_null + has_default (with a TableColumn::new constructor for the common no-constraint case), populated in build_schema_cache from ColumnDescription (a PK column counts as not-null). New dml_not_null_missing_diagnostics pass: a WARNING when a SQL INSERT's explicit column list omits a column that is NOT NULL with no DEFAULT — advisory (the engine enforces it). serial/shortid (auto-filled) and defaulted columns are excluded. Anchored on the target-table ident (no token for the omitted column). Catalog key diagnostic.not_null_missing (engine-neutral). Tests (+4): fires on omitted required column; silent when included, when defaulted, and for auto-gen serial/shortid. ~24 TableColumn literal sites updated for the two new fields (build clean). 1591 pass / 0 fail / 1 ignored. Clippy clean. All three ADR-0033 §8 DML diagnostics now implemented. Remaining 3i: cross-cut verification + #12 UPSERT DO UPDATE validation.
