Get reliable structured output on all supported Claude models

Resolved an issue where structured output support was not correctly detected for certain Claude models, causing agents to fall back to less reliable output parsing strategies even when the model fully supports structured output. Affected models now use the correct path automatically.

Fixes structured output capability detection across supported Claude model variants
Improves reliability and consistency of structured output for agents using response schemas
No configuration changes required; the fix applies automatically
