Lab 1: SSH commit signing and PR template

[rikire]

Goal

Submit Lab 1 – DevOps Foundations: configure SSH commit signing, run QuickNotes locally, add a PR template, and open the first pull request to the course repository.

Changes

• Configured global Git settings for SSH commit signing (gpg.format, user.signingkey, commit.gpgsign, tag.gpgsign).
• Ran QuickNotes locally and verified endpoints /health, /notes, and POST /notes with curl.
• Created submissions/lab1.md with required outputs, signature verification, Verified badge screenshot, and community section.
• Added .github/pull_request_template.md to the main branch of my fork.
• (Bonus) Enabled branch protection on main (require signed commits + pull request) and demonstrated rejection of an unsigned push.

Testing

• Confirmed QuickNotes responds with correct JSON using curl.exe (PowerShell) – outputs added to submissions/lab1.md.
• Verified signed commits with git log --show-signature -1 (shows "Good git signature").
• Pushed an unsigned commit to main – got remote rejection: remote: error: GH006: Protected branch update failed ... Commits must have verified signatures.
• Checked that every commit in this PR shows a green "Verified" badge on GitHub.

Checklist

• Title is a clear sentence (≤ 70 chars)
• Commits are signed (git log --show-signature)
• submissions/lab1.md updated
