…tic output - Add SetSeed() method to SchemaRenderer to allow setting custom random seed - Add SetSeed() method to MockGenerator that delegates to underlying renderer - Replace global rand usage with instance-based *rand.Rand in SchemaRenderer - Update all rand.* calls to use instance-specific random source - Add comprehensive tests for deterministic behavior with same/different seeds - Maintains full backward compatibility with existing API This enables deterministic mock generation for testing purposes while keeping existing random behavior by default.
- Initialize rand field in createSchemaRenderer() test helper - Add missing math/rand import to schema_renderer_test.go This fixes the panic that occurred when tests created empty SchemaRenderer instances without initializing the new rand field.

This enables deterministic mock generation for testing purposes while keeping existing random behavior by default.
Some background, the random behavior was convenient but made certain generation scenarios a bit hard to test. If this isn't something you think is needed lmk it's not a big deal either way
