Xavier Roche a9b16d96ea ci: poison the ASan allocator to surface missing-NUL bugs ...

Fill malloc'd and freed memory with 0xCA in the sanitize job so a buffer
fread into without NUL termination, then used as a C string, runs off into
the redzone instead of stopping at an accidental zero byte. ASan caps its
malloc fill at the first 4096 bytes by default, which lets large cache
buffers escape; max_malloc_fill_size lifts the cap. No rebuild, no source
change -- purely the test environment.
