## Summary * **What is the goal of this PR?** Fix two issues pointed out by `CodeRabbit` in #1433: 1. Free the output buffer in `readFileToMemory` on early error paths (prevents memory leaks). 2. Check `out.write()` return value in the STORED path (same as in the DEFLATED path). I can confirm both issues were real (not hallucinations). Both fixes are minimal — no behavior change on success. --- ### AI Usage Did you use AI tools to help write this code? _**< NO >**_
