fix(zod): resolve @uuid version and @time precision by argument name

[ymc9]

Problem

addStringValidation read the first optional parameter of @uuid and @time from attr.args[0]. Attribute args are emitted in source order, so @uuid(message: "custom", version: 7) put the message string at index 0 and the version was never seen — the field silently fell back to version-agnostic UUID validation. @time(message: "...", precision: 3) had the same problem.

Fix

Look the argument up by name via a small getNamedAttributeArgValue helper, matching how @length already resolves min/max. Names are always present at runtime: the language validator stamps $resolvedParam on every argument (positional ones included) and the TS schema generator emits name from it, so a name lookup covers both call styles.

Tests

New packages/zod/test/string-validation.test.ts covers @uuid with no version (any version accepted), a named version in either argument order for v4 and v7, and @time precision with message given first.

Full @zenstackhq/zod suite passes (543 tests, no type errors).

Summary by CodeRabbit

• Bug Fixes
  • UUID validation now correctly honors the named version argument regardless of its position.
  • Time validation now correctly honors the named precision argument regardless of argument order.
  • UUID validation without a specified version accepts UUIDs of any version.

📝 Walkthrough

Walkthrough

The change adds named attribute argument lookup for Zod string validation. UUID version and time precision now resolve by name, with tests covering defaults and reordered arguments.

Changes

String validation argument resolution

Layer / File(s)	Summary
Named argument resolution packages/zod/src/utils.ts	Adds a helper for named literal arguments. The @uuid and @time handlers use it for version and precision.
String validation coverage packages/zod/test/string-validation.test.ts	Tests default UUID validation, named UUID versions in different argument orders, and named time precision.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 5aaf4

This change fixes reordered named arguments but regresses positional @uuid version and @time precision forms, allowing values that existing schemas should reject. Preserve positional fallback before merging.
