What's Changed

@​firebase/ai@2.16.0

Minor Changes

• 6b17ef5 #​10319 - Fixed the issue where the SDK hardcodes invalid 'function' role, causing 400 errors during function calling on gemini-3.6-flash

Patch Changes

• 6f86596 #​10320 - Fixed a client-side validation guardrail that incorrectly blocked text/x.enum when responseSchema or responseJsonSchema was provided. The SDK now correctly accepts both application/json and text/x.enum for structured outputs.
