Move 7 Linux-specific modules into src/sys/linux/, create sys.rs dispatch hub (crosvm pattern), add Windows stubs with matching security layers (Job Objects, AppContainer, Restricted Tokens, ETW). - Move executor, monitor, workspace, sysinfo, notify to sys/linux/ - Merge isolation/lockdown.rs + rlimits.rs into sys/linux/lockdown.rs - Extract virtual_fs.rs to crate root (platform-agnostic) - Add sys/linux/policy.rs (Plan → Linux primitives compilation) - Add complete sys/windows/ stubs with Win32 API documentation - Make evalbox-sys, libc, rustix, mio Linux-only deps - Guard build.rs C payload compilation with cfg(target_os = "linux") - Add #[non_exhaustive] to ExecutorError, Event, Status - CI: Windows x86_64 + ARM64, Linux x86_64 + ARM64, cross-compile - Update deny.toml with all 4 target triples - Bump workspace version to 0.2.0

SYS_fadvise64 and SYS_sendfile do not exist in the aarch64 syscall table. Gate them with #[cfg(target_arch)] and use SYS_sendfile64 on aarch64 instead.
The Rust libc crate does not export SYS_sendfile (71) or SYS_fadvise64 (223) for aarch64-unknown-linux-gnu, despite these existing in the kernel's generic syscall table. Define them as raw constants in a `nr` module and use them in the seccomp BPF whitelist so sandboxed processes on ARM64 can call sendfile() and fadvise64() without being killed by SIGSYS. Also fix the test that asserted SYS_sendfile presence without an architecture guard.
- Remove aarch64-unknown-linux-gnu from cross-compile (redundant with native linux-arm64 runner on ubuntu-24.04-arm) - Remove windows-11-arm matrix entry (preview runner, unstable) - Keep aarch64-pc-windows-msvc as cross-compile check - Simplify Windows job to single x86_64 runner - Rename arm64 job to linux-arm64 for clarity
