The monolithic lib.rs had grown to 2600+ lines of `#[cfg(target_arch)]` blocks interleaved inside every `sys_*` function. Reading or modifying one arch's syscalls meant scrolling past thirteen others. Pull each arch's asm into `<arch>.rs`, re-exported via a single `#[cfg] #[path] mod arch;` so `lib.rs` only contains wrappers, structs, and module dispatch. Adding a new architecture now touches one new file plus one three-line mod decl.

This PR adds support for many more architectures. I was able to test on real hardware for all of these besides riscv32.
