Expands the renderer skeleton from ADR-0038's first slice to the full single-statement catalogue. Every Bucket A row round-trips through the advanced-mode walker (the §1 copy-paste contract): add column / drop column (non-cascade) / rename column / change column (SET DATA TYPE) / add constraint (not null, default, unique, check) / drop constraint (not null, default) / show data [where] [limit] / delete --all-rows / update --all-rows Adds the Expr→SQL and Value→SQL-literal renderers (ADR-0038 §5) — bare identifiers, inlined literals, NULL uppercase, standard <> for inequality — and threads `echo: Option<String>` onto the six remaining success events (DslAddColumn/DropColumn/ChangeColumn/Data/Update/Delete Succeeded) with matching runtime construction and App stash arms. `show data` is the one Bucket A row whose echo needs schema info beyond the Command (the `ORDER BY <pk>` for a limited query): the pure renderer takes the primary key as a parameter, and the runtime sources it post-execution via describe_table — gated on advanced mode + limit present, mirroring the enrich_dsl_failure describe pattern. An end-to-end test pins the describe→PK→ORDER BY glue against a real worker; the simple-mode gate and unlimited-no-lookup paths are covered too. Also fixes a contract gap surfaced while completing the catalogue: the existing create-table echo silently dropped per-column DEFAULT / CHECK, which simple-mode `create table … with pk c(ty) check (…)` does parse (ADR-0029) — so the echo was non-equivalent. The render now emits the full ADR-0029 column-constraint suffix, sharing one append_constraints helper with `add column`. Phase 2 (Bucket B — resolved-name + multi-line echoes, including `add index`), Phase 3 (category-3 prose), and the de-emphasised styled-runs polish remain deferred per ADR-0038 §8 phasing. Tests: 2000 passed / 0 failed / 1 ignored (pre-existing); clippy clean (`--all-targets -D warnings`, nursery).
