feat: Handle large schemas by stripping titles

[Konikz]

Strip titles from large schemas

Overview

Implemented a solution to prevent "too many states for serving" errors by automatically stripping titles from schemas that exceed 10,000 characters.

Changes

• Added size check for schemas (10k char limit)
• Implemented recursive title stripping for large schemas
• Added test coverage for the new functionality

Testing

All tests are passing, including new test cases for:

• Large schema handling
• Nested schema structures
• Title preservation for normal-sized schemas

Fixes #323
