Adds Dependabot configuration for GitHub Actions updates (not npm), mirroring alpheusday/envow .github/dependabot.yaml.

Included in this PR

.github/dependabot.yaml — the github-actions block from the envow config, with the npm ecosystem entry removed:

version: 2
updates:
    - package-ecosystem: "github-actions"
      directory: "/"
      schedule:
          interval: "daily"
          time: "00:00"
          timezone: "Etc/UTC"
      cooldown:
          default-days: 1
          include:
              - "*"
      commit-message:
          prefix: "chore"

Verified byte-identical to the upstream github-actions section (diff clean), single ecosystem entry, no npm.

⚠️ Follow-up required: auto-merge workflow could not be pushed

The companion .github/workflows/dependabot-merges.yaml (ported from alpheusday/envow) is authored and committed but could not be pushed to this branch. GitHub blocks writes to .github/workflows/ for credentials that lack the workflows permission:

! [remote rejected] cline/t26vwtah -> cline/t26vwtah
  (refusing to allow a GitHub App to create or update workflow
   `.github/workflows/dependabot-merges.yaml` without `workflows` permission)

A control test confirms the boundary: a non-workflow file pushed to a scratch branch succeeded, while the same push including a .github/workflows/ file was rejected. The Contents API returns 403 Resource not accessible by integration as well.

To apply it, add this file at .github/workflows/dependabot-merges.yaml (via the web UI, or a push from a credential with the workflows permission):

name: Dependabot Merges

on:
    pull_request:
        types:
            - opened
            - reopened
            - synchronize

jobs:
    approve-and-merge:
        name: Approve & Merge
        if: ${{ github.event.pull_request.user.login == 'dependabot[bot]' }}

        runs-on: ubuntu-latest

        permissions:
            contents: write
            pull-requests: write

        steps:
            - name: Fetch Dependabot metadata
              id: dependabot-metadata
              uses: dependabot/fetch-metadata@v3
              with:
                  github-token: "${{ secrets.GITHUB_TOKEN }}"

            - name: Approve PR
              run: gh pr review --approve "${{github.event.pull_request.html_url}}"
              env:
                  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

            - name: Merge PR
              run: gh pr merge --auto --squash "${{github.event.pull_request.html_url}}"
              env:
                  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

⚠️ Second prerequisite: auto-merge is disabled on this repository

gh pr merge --auto fails unless repo-level auto-merge is on. Current setting:

allow_auto_merge: false

Enable Settings → General → Pull requests → Allow auto-merge (or gh api -X PATCH repos/alpheusci/setup-python -f allow_auto_merge=true). This could not be changed from here — it returns 403, as it needs repo admin. allow_squash_merge is already true, so the --squash flag is fine.

Until both items are done, the workflow will not merge anything.
