chore(tools): update scripts, native libs, and documentation

Update tooling and documentation:
- Smoke test script with scheduler health checks
- Release cleanup script
- Native test scripts with Redis integration
- TUI SSH test script
- Performance regression detector with scheduler metrics
- Profiler with distributed tracing
- Native CMake with test targets
- Dataset hash tests
- Storage symlink resistance tests
- Configuration reference documentation updates

+- **Allowlist approach**: Only explicitly permitted syscalls are allowed
+- **Multi-architecture support**: x86_64, x86, aarch64
+- **Blocked dangerous syscalls**: ptrace, mount, umount2, reboot, kexec_load, open_by_handle_at, perf_event_open
+
+**Usage with Docker/Podman:**
+
+```bash
+# Docker with seccomp
+docker run --security-opt seccomp=configs/seccomp/default-hardened.json \
+  -v /data:/data:ro \
+  my-image:latest
