Implement the linkat syscall and link() filesystem operation to enable hard links in AgentFS. This fixes the cargo incremental compilation warning about hard linking files failing. Changes: - Add link() method to FileSystem trait with implementations for AgentFS (creates new dentry pointing to same inode), HostFS (delegates to kernel), and OverlayFS (with copy-up semantics) - Add link() to VFS trait and SqliteVfs implementation - Add handle_linkat syscall handler in ptrace sandbox with path translation for both virtual VFS and bind mounts - Implement link() in FUSE filesystem - Add comprehensive syscall test (test-link.c) covering hard link creation, inode sharing, nlink count, data sharing, and error cases
