chat : honor json_schema in Ling 3.0 parser (#29813)

• chat : honor json_schema in Ling 3.0 parser

Ling 3.0 only built a grammar for tool calls and did not handle inputs.json_schema, so response_format requests were left unconstrained.

Add an eager response-format grammar path with precedence over tools, following the existing parser patterns. Require before JSON when thinking is enabled and do not allow trailing prose after the JSON response.

Fixes #29652.
