Context Management And State Isolation For Concurrent Validations

LLM output validation framework with auto-correction.

Unique: Uses thread-local and async-local storage to automatically isolate validation context across concurrent executions, enabling safe reuse of Guard instances without explicit synchronization. Context cleanup is automatic and transparent to the user.

vs others: More efficient than creating new Guard instances per request because context isolation is built-in; more reliable than manual synchronization because isolation is automatic and less error-prone.
