Feature: GitHub PR template

[idf-io]

Summary

Adds a pull request template so PR descriptions are consistent and reviewers see the relevant checks. GitHub's web UI can't choose between several templates, so this is a single template with one section per change type (feature, bug fix, tests, docs, refactor/style, CI/CD, breaking changes/dependencies). Contributors delete the sections that don't apply. AGENTS.md now points to the template and adds high-level directives for writing PRs.

General checklist

• Branch name and commit subjects follow the repo conventions
• HISTORY.md updated under [Unreleased] (or N/A: no user-facing change). N/A: contributor tooling only
• CI is green (flake8, pylint, pytest)

📚 Documentation

What changed:

• .github/pull_request_template.md (new): a shared header (summary, related issues, general checklist), then optional per-type sections. Each section has guidance in HTML comments and a short ProteoPy-specific checklist. Detailed coding rules stay in AGENTS.md and are referenced, not repeated.

• AGENTS.md, Commit and Pull Request Guidelines: refers to the template and adds directives on correctness, conciseness, readability, scope and impact. Removes the old "Test/lint outputs" requirement, since CI runs the checks and the template only asks for a checkbox.

• Sphinx build runs without new warnings. N/A: no Sphinx sources touched

• Notebooks re-run top to bottom; outputs are current. N/A: no notebooks touched

• Examples use import proteopy as pr

---

Notes for reviewers

• The template only takes effect once merged into main.
• AGENTS.md contains the Commit and Pull Request Guidelines section twice (along with several other duplicated sections). Both copies were updated identically. Removing the duplication is left for a separate PR.
• No Python files changed. The pre-push pytest hook was skipped locally (SKIP=pytest); all lint hooks passed.
