constraints: CHECK-violation friendly error + typing-surface matrix (ADR-0029 §10)

Browse Source 
Completes ADR-0029's implementation: the friendly-error layer
now names the rule a CHECK violation broke, and the
typing-surface matrix covers the whole constraint grammar.

CHECK-violation friendly error (ADR-0029 §10):
- enrich_dsl_failure gains a CHECK branch — it reads the column
  from the engine's `CHECK constraint failed: <column>`
  message, then resolves the table, the offending value, and
  the column's compiled CHECK expression.
- FailureContext / TranslateContext carry the resolved
  check_rule; translate_check renders "the value <v> breaks the
  rule `<rule>`" when it is known, falling back to the plain
  hint otherwise.

Typing-surface matrix: a new `constraints` submodule, 14 cells
covering the create-table / add-column constraint suffix and
the add-constraint / drop-constraint commands (174 → 188).

16 tests added (1 translate unit, 1 enrichment integration, 14
matrix cells).
