This change introduces an LRU cache to store the SHA-256 hashes of executables computed during execve syscalls. The cache key is based on the file's mount ID, inode number, size, and modification time. This prevents redundant hash computations for frequently executed binaries. The cache size is configurable via SetMaxExecveSha256CacheEntries. PiperOrigin-RevId: 948432440
