Module json_repair 

Tolerant JSON parsing for LLM outputs.

LLMs frequently produce malformed JSON: trailing commas, unescaped quotes, incomplete brackets, or markdown-wrapped code blocks. Historically this logic lived in lc-core, but ToolCall::parse_arguments (in this crate) parses the same kind of LLM-generated JSON and cannot depend on lc-core. So the repair pipeline lives here so that every parser of LLM JSON — in lc-shared and lc-core alike — converges on a single tolerant parser.
