Fixed
- jcode model validation freeze — Fixed terminal freeze when launching jcode with custom models (e.g. GPT OSS 120B via NVIDIA NIM). jcode has a hardcoded model whitelist that rejected non-standard model names passed via
--modelflag, causing the REPL to start without a valid model and hang unresponsively. Now usesJCODE_MODELenv var instead, which bypasses the validation and allows any model name to work correctly.
