[P2] Backward-compatibility regression: gemini-2.5-pro-preview-03-25 no longer includes maxThinkingTokens and supportsReasoningBudget. Losing these flags can disable reasoning-budget controls for users pinned to this version. Unless docs confirm the capability was removed, keep these fields to preserve behavior.

Suggested fix:
