[WIP] Update PR squash guard workflow to English

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

Rewrite the existing PR squash guard workflow to English and open a new PR with the changes.

Context:

• There is already a workflow file introduced in a prior PR at .github/workflows/pr-squash-guard.yml that checks PR commit counts and fails for specific authors when there are more than one commit.

Task:

• Ensure a workflow exists at .github/workflows/pr-squash-guard.yml that enforces: any pull request authored by GitHub users "Lemi257" or "bellus869" must have exactly one commit. If the PR has more than one commit, the job fails.
• Rewrite all workflow names, job/step names, log messages, and the failure message to English.
• Keep functionality unchanged (same authors, same event triggers, same minimal permissions, robust for PRs from forks). Use actions/github-script with the REST API to fetch commit count when not present in the payload.
• If the file already exists, update it in-place; if it doesn't, create it.
• Open a new PR with the English naming and messaging.

Workflow requirements:

• File path: .github/workflows/pr-squash-guard.yml
• Triggers: pull_request with types [opened, synchronize, reopened, ready_for_review, edited]
• Permissions: contents: read, pull-requests: read
• Job name (English): "Check commit count for selected authors"
• Step name (English): "Check commit count and fail if necessary"
• Authors list: ["Lemi257", "bellus869"]
• Failure message (English): "This pull request must be squashed into a single commit. Found {commits} commit(s)."
• Informational logs in English.

Suggested implementation (you may adopt as-is):

name: PR squash guard

on:
pull_request:
types: [opened, synchronize, reopened, ready_for_review, edited]

permissions:

pull-requests: read

const targetAuthors = ["Lemi257", "bellus869"]; // PRs by these authors must be squashed to 1 commit
const pr = context.payload.pull_request;
const author = pr?.user?.login;
const number = pr?.number;

        if (!author || !number) {
          core.info("Unable to determine author or PR number — skipping check.");
          return;
        }

        if (!targetAuthors.includes(author)) {
          core.info(`Author ${author} is not in the target list — check does not apply.`);
          return;
        }

        let commits = typeof pr.commits === 'number' ? pr.commits : undefined;
        if (typeof commits !== 'number') {
          const { data: prData } = await github.rest.pulls.get({
            owner: context.repo.owner,
            repo: context.repo.repo,
            pull_number: number,
          });
          commits = prData.commits;
        }

        core.info(`PR #${number} by ${author} has ${commits} commit(s).`);

        if (commits > 1) {
          core.setFailed(`This pull request must be squashed into a single commit. Found ${commits} commit(s).`);
        } else {
          core.info("Commit count is OK (<= 1).");
        }

PR details:

• Branch name suggestion: chore/workflow-pr-squash-guard-en
• PR title: "Add PR squash guard workflow for specific authors (English)"
• PR description: Explain in English that the workflow runs on pull_request events, checks the number of commits specifically for authors Lemi257 and bellus869, and fails if there is more than one commit to enforce squash merges for those authors.
