Updates the flowey `OPENVMM_DEPS` pin from `0.3.0-29` to `0.3.0-33` and aligns the nix derivations with what flowey now uses.

Changes

  • `flowey/flowey_lib_hvlite/src/_jobs/cfg_versions.rs`: bump `OPENVMM_DEPS` to `0.3.0-33`. This single const drives the flowey `resolve_openvmm_deps`, `resolve_openvmm_test_linux_kernel`, and `resolve_openvmm_test_initrd` nodes, so the test-kernel and test-initrd downloads bump alongside it.

  • `nix/openvmm_deps.nix`: bump from the stale `0.1.0-20250403.3` pin to `0.3.0-33`, switch the artifact extension from `.tar.bz2` to `.tar.gz` (the `0.3.0-x` releases only ship `.tar.gz`), and update both sha256 hashes. The new openvmm-deps archive no longer bundles `vmlinux`/`initrd` — those moved to separate `openvmm-test-linux-` and `openvmm-test-initrd-` release assets that flowey already handles via dedicated resolver nodes. The nix `installPhase` here only ever consumed `sysroot.tar.gz` / `*.cpio.gz` / `petritools.erofs`, all of which are still at the same top-level paths in the new archive.

  • `nix/openhcl_kernel.nix`: bump from `6.18.0.2` to `6.18.0.3` to match `OPENHCL_KERNEL_DEV_VERSION` / `OPENHCL_KERNEL_STABLE_VERSION` in `cfg_versions.rs` (the `6.18.0.2` release was unreachable from the pinned URL, breaking `nix-shell --pure`). All five hashes recomputed (3 std + 2 cvm).

Validation

  • `nix-shell --pure shell.nix` succeeded end-to-end against the pinned nixpkgs; all six kernel variants (x64/arm64 × std/cvm/dev) plus both openvmm-deps derivations build cleanly.
  • `cargo clippy --all-targets -p flowey_lib_hvlite` — clean
  • `cargo doc --no-deps -p flowey_lib_hvlite` — clean
  • `cargo xtask fmt --fix` — no changes (also re-ran flowey `regen`, no YAML diffs)

Updates the flowey OPENVMM_DEPS pin from 0.3.0-29 to 0.3.0-33 and
aligns the nix derivations with what flowey now uses:

- nix/openvmm_deps.nix: bump from the stale 0.1.0-20250403.3 pin to
  0.3.0-33, switch the artifact extension from .tar.bz2 to .tar.gz
  (the 0.3.0-x releases only ship .tar.gz), and update both sha256
  hashes. The new openvmm-deps archive no longer bundles vmlinux/
  initrd (those moved to separate openvmm-test-linux-* and
  openvmm-test-initrd-* release assets, which flowey already handles
  via dedicated resolver nodes), but the installPhase here only ever
  consumed sysroot.tar.gz / *.cpio.gz / petritools.erofs so no
  layout changes are needed.

- nix/openhcl_kernel.nix: bump from 6.18.0.2 to 6.18.0.3 to match
  OPENHCL_KERNEL_DEV_VERSION / OPENHCL_KERNEL_STABLE_VERSION in
  cfg_versions.rs (the 6.18.0.2 release was unreachable from the
  pinned URL, breaking nix-shell --pure). All five hashes
  recomputed (3 std + 2 cvm).

Validated end-to-end with nix-shell --pure shell.nix; all six
kernel variants plus both openvmm-deps derivations build cleanly
against the pinned nixpkgs.
