Subject: [PATCH] ci: remove auto-merge workflow (use native Enable auto-merge)

auto-merge automation was retired in agiletec (#551). Standardize on
GitHub's native per-PR "Enable auto-merge" instead of a CI workflow.

-# Prerequisites on the caller repo:
-#   * the `agiletec-automerge` GitHub App is installed on it, with
-#     Contents: write AND Pull requests: write — enabling auto-merge
-#     pre-authorizes a future merge, so contents:write is required too
-#     (a pull-requests-only token gets FORBIDDEN from the API)
-#   * "Allow auto-merge" is enabled in the repo settings
-#
-# The default GITHUB_TOKEN cannot enable auto-merge — it fails with
-# "Resource not accessible by integration". A token minted from the
-# purpose-built agiletec-automerge App is used instead; that App carries
-# only contents + pull-requests write — no admin, no actions, no
-# secrets — unlike the deploy-bumper App, kept to agile-server alone.
