`create table … with pk` now parses the column-constraint
suffix; combined with the commit-1 db layer, a constrained
table works end to end.
- A shared constraint-suffix grammar fragment — `not null`,
`unique`, `default <literal>` — sits after each column's
`(type)` group; `build_create_table` walks the matched path
per column and folds the constraints into `ColumnSpec`.
- §9 redundancy check: every `with pk` column is a primary-key
column, so `not null` (any) and `unique` (single-column PK)
are rejected with a friendly error
(`parse.custom.constraint_redundant_on_pk`).
- `project.yaml` round-trip: `ColumnSchema` gains `not_null` /
`default`; the YAML reader/writer and `build_read_schema`
carry them, so `rebuild` / `export` / `import` preserve
constraints.
- ADR-0029 §2.1's example corrected — `create table` columns
are all PK columns, so its suffix is for `default` / `check`;
`docs/simple-mode-limitations.md` records that non-PK
columns at create time need advanced mode.
CHECK is deferred to the next commit. 1184 tests pass (+7);
clippy clean.
The C5a design: a stratified, recursive WHERE-expression
grammar (AND/OR/NOT, comparisons, LIKE, IS NULL, IN,
BETWEEN) for update / delete / show-data filters; show
data gains optional `where` and `limit`. Adds the
`Subgrammar` reference-following grammar node and a
recursive `Expr` AST, built selectively for the
expression fragment.
