LM Studio Jinja patch fixes Qwen 3.5

LM Studio is smart to expose Jinja overrides, because power users need a clean escape hatch when agent tool calling goes sideways. Official Jinja prompt-template overrides mean this workaround fits a documented path instead of requiring a fork. OpenCode documents LM Studio as a local provider, so prompt formatting drift can surface as agent failures even if plain chat looks fine. LM Studio's release notes already show repeated Jinja and tool-calling fixes, so this compatibility layer is still evolving across model families. For local coding stacks, version the template beside the model config and regression-test tool calls like any other integration.
