Subject: [PATCH 1/2] Add mirror-clone.sh wrapper for sjtug/mirror-clone

Wrap sjtug/mirror-clone binary so multiple tunasync jobs can share one
script. The wrapper exposes three layered environment variables:

  - TUNASYNC_MIRRORCLONE_OPTIONS: mirror-clone options before source
  - TUNASYNC_MIRRORCLONE_SOURCE:  required source plugin name
  - TUNASYNC_MIRRORCLONE_ARGS:    plugin-specific arguments

This pattern is used by NJU mirror to drive ghcup, crates.io and other
mirror-clone-based jobs from a single shared script.

Subject: [PATCH 2/2] mirror-clone.sh: use _here-based binary lookup, add
 pipefail

Follow the convention used by chef.sh/cvmfs.sh/bazel-apt.sh: locate the
helper binary relative to the script directory (${_here}/mirror-clone)
with an optional MIRRORCLONE_BIN override, instead of a hard-coded
/home/mirror-clone path.

Also switch from 'set -eu' to 'set -euo pipefail'.
