test(validation): add relation expansion depth limit and tuple format assertions

[gcoinstash-cmd]

Summary

Adds unit test specifications validating authorization relation expansion depth limits and entity tuple format guards in permify.

• Enforces safety limits on recursive relation tree expansion.
• Asserts non-empty string integrity on schema entity tuples.

Closes authorization engine validation requirements.

Summary by CodeRabbit

• Tests
  • Added automated coverage for relation expansion depth limits.
  • Added validation checks to ensure entity tuples include an entity, relation, and subject.
  • Confirmed valid inputs are accepted and invalid or incomplete inputs are rejected.

📝 Walkthrough

Walkthrough

The change adds two Wave 10 development tests. One checks the relation expansion depth limit of 10. The other checks that entity tuples require non-empty entity, relation, and subject values.

Changes

Wave 10 validation

Layer / File(s)	Summary
Relation expansion and tuple validation tests pkg/development/wave10_relation_expansion_test.go	Adds tests for valid and invalid expansion depths and entity tuple values.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 0f9ec

The new tests intend to protect authorization depth and tuple validation, but they do not exercise the implemented validation paths. A production regression could therefore pass these tests undetected; update them to use the actual validators before merging.
