Add seccomp feature flag (seccompiler + libc, Linux-only, optional). When compiled with --features seccomp, weft-runtime installs a SECCOMP_MODE_FILTER immediately after argument parsing, before any package resolution or WASM execution. Filter strategy: default-allow with explicit KillProcess rules for high-risk syscalls a WASM runtime process has no legitimate need for: ptrace, process_vm_readv/writev, kexec_load, personality, syslog, reboot, mount/umount2, setuid/setgid/setreuid/setregid/setresuid/ setresgid, chroot, pivot_root, init_module/finit_module/delete_module, bpf, perf_event_open, acct. The feature is off by default so the standard build and tests are unaffected. Enable in production service builds with --features seccomp.
