test: add coverage for entity-kinds.ts hydration branches

[EmaToplek]

Summary

Adds test coverage for tableEntityKind.construct in packages/2-sql/1-core/contract/src/entity-kinds.ts, covering both hydration paths (already-constructed Index/CheckConstraint instances passed through vs. serialized JSON forms hydrated via indexInputFromSerialized/checkConstraintInputFromSerialized), plus the branch where checks is entirely absent from the input.

• entity-kinds.ts: 100% statements/branches/functions/lines (up from 83%/43%/60%/83%)

Summary by CodeRabbit

• Tests
  • Added coverage confirming that existing indexes and check constraints remain unchanged during table construction.
  • Added tests verifying that serialized indexes and check constraints are restored correctly.
  • Verified that tables omit check constraints when none are provided.
  • Confirmed that supplied index and check constraint objects retain their original identity.

📝 Walkthrough

Walkthrough

The entity-kind tests now cover index and check constraint preservation, serialized input hydration, parsed names, and omitted checks.

Constraint preservation and hydration packages/2-sql/1-core/contract/test/entity-kinds.test.ts	The tests verify that table construction preserves existing Index and CheckConstraint instances, hydrates serialized inputs into IR instances, parses their names, and omits checks when none are provided.
