* fix(proxy): invoke post-call guardrails on pass-through endpoint responses (#20270) Wire post_call_success_hook into non-streaming pass-through response path, gated on explicit guardrail config (opt-in only, no backwards-compat break). - Call post_call_success_hook after reading non-streaming response body - Build enriched hook_data with guardrails metadata and litellm_logging_obj at call site (avoids mutation of _parsed_body which is shared by logging) - Handle ModifyResponseException with provider-agnostic error envelope, post_call_failure_hook, and defensive try/except - Strip stale content-length when guardrail modifies response body - Move ModifyResponseException to litellm.exceptions to break cyclic import; re-export from custom_guardrail for backwards compat - Add call_type fallback in UnifiedLLMGuardrails for pass-through endpoints using CallTypes.pass_through.value enum * test: add unit tests for pass-through post-call guardrails 5 tests covering the post-call guardrail invocation on pass-through endpoints: - post_call_success_hook fires when guardrails configured - post_call_success_hook skipped when no guardrails (backwards compat) - ModifyResponseException returns 200 with provider-agnostic error - UnifiedLLMGuardrails resolves call_type from logging_obj for pass-through - ModifyResponseException re-export from custom_guardrail stays in sync
