refactor(s390x): export rustc-symlink overlay + add formatter; refresh pins

Lift the s390x rustc symlink_file patch overlay into overlays.s390xRustcSymlink
so nixos-ci consumes one definition (patch travels with it) instead of
duplicating it. Add nixfmt-rfc-style formatter. Refresh fleet-pins + parity
inputs to HEAD so the lock collapses to a single nixpkgs (1c3fe55).

# Update flow for gitea-local-fork driven by passthru.updateScript.
# Invoked by `nix-update --use-update-script gitea-local-fork`.
#
# Source fork: /home/oleks/projects/gitea
# Source remote: https://git.oleks.space/oleks/gitea.git (named `oleks` locally)
# Tracked branch: oleks/main (formerly `feat/projects-api`, renamed 2026-05-13)
#
# nix-update with --version=branch=X constructs the new version as
# `<latest-tag>-unstable-<date>` where <latest-tag> is the most recent
# tag on the remote. If we leave an old `v1.26.0-unstable-<date>` tag
# from a previous run on the gitea fork, nix-update will pick that
# as <latest-tag> and we end up with double suffixes. So:
#
# 0. Delete any prior `*-unstable-*` tag on the gitea fork (local + remote).
# 1. Run nix-update default flow: it now sees only clean semver tags
# (v1.26.0 etc.), constructs `1.26.0-unstable-<commit-date>`.
# 2. Tag the gitea fork at the new rev with v<version>, push the tag.
# 3. Commit flake-hub's package.nix change, push to origin.
