CI: Mirror Aether-gate fails on every run — MIRROR_SYNC_TOKEN lacks the `workflow` scope (mirror 86 commits behind)

Mirror Aether-gate has been failing on every scheduled run since well before the
visible run history begins, so aethersdr/Aether-gate has drifted a long way behind
its upstream. Raising it because the job is deliberately quiet — it only surfaces in
the Actions tab, and it no-ops rather than failing when unconfigured, so a real failure
looks much like the intended silence.

The error

From the most recent run (33133278635):

Upstream commits contain workflow changes, which require the `workflow` scope
or permission to merge. To request it, run: gh auth refresh -s workflow

MIRROR_SYNC_TOKEN is authorised for contents but not workflows. GitHub refuses a
sync outright when any pending commit touches .github/workflows/, so this is not
limited to the commits that caused it — every subsequent commit is blocked too.

Two commits upstream trip it, both mine, around 15–16 July: one added
.github/workflows/docker.yml, one modified .github/workflows/tests.yml.

Current state

Fix

Add the workflow scope to the PAT behind MIRROR_SYNC_TOKEN. The backlog should
fast-forward on the next scheduled run; no change to
.github/workflows/mirror-aether-gate.yml
is needed.

Why it may be worth doing rather than leaving

The mirror predates the HPSDR Protocol-1 adapter, the RX audio path, the IQ
conjugation fix (inverted sideband) and the IC-9700 CI-V SET-menu work.

It also predates 57d6c67c, which retracts an earlier stream-starvation claim as a
measurement error — so the org's copy currently carries the claim without the
retraction. Anyone reading aethersdr/Aether-gate today is reading July, including
one conclusion that has since been withdrawn.

No objection at all if the answer is to retire the mirror instead of maintaining a
token for it — nigelfenton/Aether-gate
is public and current either way. Flagging it rather than assuming which way you'd want
it to go.

Filed outside the issue templates deliberately: bug_report.yml requires radio model,
OS and AetherSDR version, none of which apply to a CI credential scope.

Start with .github/workflows/mirror-aether-gate.yml and failed run 33133278635; compare the token permissions with the reported workflow-scope error. Confirm the chosen outcome—restore the mirror or retire it—and, if maintained, verify a scheduled run synchronizes the 86-commit backlog.
