chore: remove accidentally committed nginx tarball and add .gitignore

[Copilot]

• Create .github/workflows/test-nginx-master.yml — mirrors the 1.30 workflow but builds nginx from the master branch HEAD

Original prompt

Task

On the existing branch copilot/add-ci-workflow-for-nginx (PR #3), there is an accidentally committed binary file release-1.30.0.tar.gz (blob SHA: f4c3d0c35594c956b3761e6ce7a7f5f415fc3486) that must be removed.

Do NOT create a new PR. Push directly to the existing branch copilot/add-ci-workflow-for-nginx.

Changes required

1. Delete release-1.30.0.tar.gz from the branch root.
2. Create or update .gitignore in the repo root to add an entry ignoring *.tar.gz files (and any other common build artifacts like release-*.tar.gz) so this cannot happen again.

The .gitignore should include at minimum:

# nginx source tarballs
*.tar.gz
release-*/

Commit message should be: chore: remove accidentally committed nginx tarball and add .gitignore

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: test your changes and run the new test

Assistant: Here's the current status of PR #3:

PR Status

Both CI workflows are waiting for approval (action_required) — GitHub requires a maintainer to authorize workflow runs for this PR before they execute. This is a standard GitHub Actions security gate for pull requests from first-time contributors/bots.

Workflow	Run	Status
test nginx 1.30	#9	⏸️ action_required
test cleanup-null (fault injection)	#2	⏸️ action_required

What Needs to Happen

To let CI run, you (as repo maintainer) need to approve the workflow runs for this PR:

1. Go to the Actions tab or directly to the PR checks
2. Click "Approve and run" for the pending workflow runs

⚠️ One Issue to Fix First

There's an accidental file committed in the PR: release-1.30.0.tar.gz — the nginx source tarball (from the build step in the workflow) was accidentally committed into the branch. This should be removed before merging.

Would you like me to:

1. Remove release-1.30.0.tar.gz from the branch, and
2. Add a .gitignore entry to prevent it happening again?

User: yes remove the file. and then re run the test

Assistant: I don't have a native delete-file tool, but I'll use the coding agent to push a commit to the existing PR branch that removes the tarball and adds a .gitignore entry to prevent it from being committed again.

Assistant: We're waiting for you to respond to the tool confirmation dialog — once you approve it, the coding agent will remove release-1.30.0.tar.gz from the PR branch and add a .gitignore entry, which will also trigger a fresh CI run automatically on the updated commit.

Merge conflicts resolved in c8e66f0. The conflict in test-nginx-master.yml was resolved by taking the base branch's more complete version (two-job layout with permissions: contents: read, the fault-injection test-cleanup-null job, and the test step that excludes 004-cleanup-null.t). The base branch's t/004-cleanup-null.t (using a BEGIN block for early skip) and the deletion of the now-superseded test-cleanup-null.yml were also brought in.
