bug: nightly 🔄 Sync Labels is permanently red (dot-template is not inert; labels.yaml removed from actions)

Problem

The scheduled 🔄 Sync Labels workflow went red on main at 2026-07-03T00:26Z and will fail every night from now on: https://github.com/devantler-tech/reusable-workflows/actions/runs/28630213556

Root cause chain:

1. The workflow file is .github/workflows/.sync-labels.yaml — the dot-prefixed template. Dot-prefixed workflow files are not inert: GitHub Actions registers and schedules them like any other workflow (it has run nightly for months).
2. It calls devantler-tech/actions/sync-github-labels@…v7.1.3, which fetches https://raw.githubusercontent.com/devantler-tech/actions/refs/heads/main/.github/labels.yaml at runtime.
3. Label management moved to declarative Crossplane Label resources in devantler-tech/.github (Remove the EndBug/label-sync mechanism (superseded by declarative IssueLabels) .github#58, acceptance completed 2026-07-02), and labels.yaml + the sync-github-labels action were removed from actions main → the fetch now 404s, permanently.

Proposed direction

Labels are Crossplane-managed, so this workflow is redundant, not just broken. Per the standing direction that no work lands in this repo (it is being merged into actions and archived), the fix is a maintainer one-click, not a PR:

• One-click: disable the workflow — gh workflow disable ".github/workflows/.sync-labels.yaml" --repo devantler-tech/reusable-workflows (or Actions UI → 🔄 Sync Labels → Disable workflow).
• The file itself gets swept when the repo is archived (see the consumer-repoint epic on actions).

Size

One click. Filed for the record + so the nightly red is not mistaken for a real regression.
