Companion to #727 (go: 1.26.6 -> 1.26.8). Both exist for the same reason: routine package sweeps have started landing upstream releases whose toolchain floor is above what we ship.

Why

pkgs#725 failed on both arches within seconds:

error: rustc 1.97.1 is not supported by the following packages:
  atuin@18.22.0 requires rustc 1.98.0

atuin is held at 18.19.0 on that branch until this lands, which let the other six updates in that stack through. 1.98.1 is current stable and one patch above atuin's floor.

The source mirror

packages/rust pulls from gs://minimal-staging-archives/, which did not have 1.98.1 — the mirror topped out at 1.97.1. Added it:

1. downloaded rustc-1.98.1-src.tar.xz from static.rust-lang.org (244,440,824 bytes)
2. verified its sha256 against upstream's published .sha256 → be1816e7…
3. uploaded to the archive bucket
4. re-read it back out of the bucket and re-hashed → same digest

That matches the existing convention: the mirrored 1.97.1 object hashes to exactly the sha256 upstream publishes, so the recipe hash is upstream's hash.

Scope

Version and source hash only. bootstrap.toml pins channel = "stable" with no version, and build.sh has no version references, so nothing else in the recipe moves.

Scheduling note

This rotates spec hashes for the packages that import rust, so expect a rebuild wave. packages/rust/build.ncl is also rewritten by the hex0 bootstrap work in #667 — whichever of the two lands second will need a rebase.
