This change optimizes the directory listing performance in
glaive_core.cby parallelizing thefstatatcalls. Previously,nativeFillBufferperformedgetdents64andfstatatserially for each file, which caused significant delays in large directories due to I/O latency. The new implementation gathers all filenames first, then uses a thread pool to performfstatatin parallel, and finally sorts and outputs the results. This ensures 'instant feedback' and better responsiveness. Robustness checks forpthread_createand memory leak fixes were also applied.PR created automatically by Jules for task 8531284504720419051 started by @mewmix
