release: reconcile syscall with origin; defer the native toolchain

syscall
  submodule/syscall had diverged from origin -- 18 local commits against
  19 on the remote, with matching subjects and different SHAs, i.e. the
  local branch had been rewritten at some point. Rather than force-push
  and discard 19 published commits, rebased local onto
  origin/submodule/syscall. git absorbed 16 duplicates by patch-id,
  leaving two genuinely local commits (NUMA support, which origin does
  not have at all, and the 0.3.2 version bump).

  Verified no work was lost: the rebased tree is byte-for-byte identical
  to the pre-rebase state apart from the Cargo.toml version line, and a
  backup/pre-rebase-* branch is kept. Two Cargo.toml conflicts were
  version-label collisions only, resolved to 0.9.1+rb0.3.1 mid-series and
  0.9.1+rb0.3.2 at the tip, per the Cat 2 convention. The push is now a
  fast-forward and the gitlink is updated to the rebased SHA.

native toolchain
  gcc-native and rust-native set to "ignore" -- explicit operator
  decision, 2026-08-03: 'Treat gcc-native/rust-native as a separate
  workstream, explicitly deferred by me, for now.' That is the one
  condition AGENTS.md ABSOLUTE RULE permits an exclusion under. It is not
  an agent-initiated removal, and not a repeat of the 'not needed for
  greeter proof' hand-wave that previously hid real breakage -- that
  suppression was reverted first, which is how the defects were found.

  binutils-native and llvm-native stay in the target; llvm-native is
  required for libclc and Mesa's iris/radeonsi CLC path. The recipes for
  the deferred pair are fixed and committed, not reverted.
