restructure: rsnix kernel + shell crate + rsdos entry point

Architecture:
  rs-dos/  (workspace root, was raisernics/)
  ├── rsnix/     — kernel lib crate (uefi, serial, gop, ps2, interrupts, memory)
  ├── shell/     — shell lib crate (prompt, commands, line input)
  ├── rsdos/     — binary crate (efi_main, init, panic handler)
  └── rsboot/    — future git submodule

No functional changes — boots to shell prompt identically.
Version auto-pulled from Cargo.toml via env!("CARGO_PKG_VERSION").
