release: v0.8.4 — M2-12 Linux bzImage boot smoke

Banks the M2-12 work that shipped on main as commit 9050694.
No functional changes since v0.8.3.

Highlights of the v0.8.4 release (vs v0.8.3):

- New zamak-linux-stub-kernel crate produces a spec-compliant
  protocol-2.15 bzImage; CI `qemu-smoke` now runs three UEFI
  cases (boot-smoke, linux-bzimage, asm-verification) all green.
- zamak-core::linux_boot gains prepare_linux_boot orchestrator
  + 6 unit tests (20 total in the module).
- zamak-uefi dispatches on entry.protocol (linux vs limine) and
  gained a Linux-specific handoff (RSI=boot_params, no CR3
  swap — Linux builds over UEFI's identity map).

12 workspace crates bumped 0.8.3 → 0.8.4.
