Contributor guide

Research direction
Investigate how YugabyteDB handles SIGSEGV signals and how ASAN/TSAN affect core dump generation. Check the sanitizer flags (e.g., `handle sigsegv`, `abort on error`) from the linked documentation. Verify system ulimit and core dump settings. Test with a minimal C program to confirm core dump behavior in ASAN mode.
