Derived from Podman's default profile, stripped of capability-conditional
rules (we never grant capabilities), argument filters, and the explicit
EPERM block. Dangerous syscalls (mount, unshare, ptrace, bpf,
perf_event_open, io_uring_*, keyctl, kexec_*, ...) fall through to the
default ENOSYS action, which also keeps glibc's clone3 -> clone fallback
working. x86_64 and aarch64 are supported; other archs error out.
Toggle with --seccomp / --no-seccomp or seccomp = <bool> in config.
