Samanvya Tripathi	af5c13841f	common : fix tool call type detection for nullable and enum schemas (#21327) ... * common : fix tool call type detection for nullable and enum schemas * common, tests : fix grammar delegation for nullable/enum schemas and add tests Fix enum type inference to scan all enum values (not just index 0) so schemas like {"enum": [0, "celsius"]} correctly detect string type. Fix schema_delegates in peg-parser to handle nullable type arrays (["string", "null"]) and typeless enum schemas in raw mode, allowing the tagged parser to use raw text instead of JSON-formatted strings. Add test cases for Qwen3-Coder (TAG_WITH_TAGGED format): - nullable string ["string", "null"] - nullable string with null first ["null", "string"] - nullable integer ["integer", "null"] - enum without explicit type key	2026-04-03 17:51:23 +02:00
