chore: enforce semantic PR title validation

[yordis]

Summary

• Adds amannn/action-semantic-pull-request@v5 as a new job in the PR workflow
• Validates that PR titles follow the Conventional Commits spec
• Restricts allowed types to feat, fix, and chore
• Subjects must not start with an uppercase character
• WIP PRs are allowed; single-commit validation is disabled

Test plan

• Open a PR with a non-conforming title (e.g. Update readme) — check should fail
• Open a PR with a disallowed type (e.g. docs: update readme) — check should fail
• Open a PR with a valid title (e.g. feat: add something) — check should pass

PR Summary

Low Risk
Workflow-only change that affects CI gating; main risk is unintended PR check failures due to stricter title rules.

Overview
Adds a new semantic-pr-title job to the PR GitHub Actions workflow to enforce Conventional-Commit-style PR titles.

The check restricts allowed types to feat/fix/chore, makes scope optional, rejects subjects starting with an uppercase letter, and allows WIP titles while skipping single-commit validation.
