docs: add pull request template

[hasansezertasan]

Description

Adds .github/PULL_REQUEST_TEMPLATE.md so new PRs are pre-populated with a consistent structure: Code of Conduct / contribution links, a Description section, and a Closes section for issue linking.

Content adopted verbatim from #16 (the copier-based PR), matching the maintainers' latest intent. Note this template is intentionally minimal — the older checklist (coverage/docs/pre-commit/tests) was dropped in #16, and this PR preserves that decision.

Closes

• Closes docs: add Pull Request template #25

Assessment against linked issues

Issue	Objective	Addressed	Explanation
#25	Add a .github/PULL_REQUEST_TEMPLATE.md file so new pull requests use a consistent template.	✅
#25	Include in the pull request template: links to the Code of Conduct and contribution guidelines, a Description section, and a section for closing/linked issues.	✅
#25	Add a checklist to the pull request template covering 100% test coverage, documentation updates, running pre-commit, and running tests.	❌	The PR explicitly states that the older checklist (coverage/docs/pre-commit/tests) was dropped in the upstream template and therefore is not included; the added template does not contain any checklist items.

Hey - I've left some high level feedback:

• Consider replacing the literal '-' under the Description section with a brief HTML comment prompt (e.g., what details to include) so new PR authors aren’t tempted to leave the placeholder as-is.
