perf(sourcemap): pre allocate String buf while encoding (#4476) I'm trying llama3.1:70b following [local-ai-copilot](https://developer.ibm.com/tutorials/awb-local-ai-copilot-ibm-granite-code-ollama-continue/) to find some potential performance improvement. The code was not completed by AI; it only identified potential optimizations, which I am testing for effectiveness.
