chore(ci): enforce conventional commit format on PR titles

[Copilot]

release-please only picks up commits that follow conventional commit conventions. Without a CI gate, PRs merged with non-conforming titles are silently excluded from changelogs and releases.

Changes

• New workflow .github/workflows/pr-title.yml — validates PR titles against the Conventional Commits spec using amannn/action-semantic-pull-request@v5
  • Triggers on pull_request_target (opened, edited, synchronize, reopened) so the check re-runs whenever the title is updated and stays fresh for branch protection requirements
  • Requires only pull-requests: read permission

Valid title examples:

feat(api): add pagination to provider list
fix: handle null providerId in metrics labels
chore(ci): update workflow permissions

This section details on the original issue you should resolve

<issue_title>Ensure PR titles have a conventional commit title</issue_title>
<issue_description>## Done Criteria
Ensure each PR title follows conventional commit conventions. If it doesn't, a CI check should fail.

Why Important

release-please only includes commits that follow conventional commit conventions. We want all of our PRs getting indicated in the release-please list, which means all PRs that are going to be squashed should have conventional commits.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/amannn/action-semantic-pull-request/git/ref/tags/v5.5.3
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
• https://api.github.com/repos/amannn/action-semantic-pull-request/releases/latest
  • Triggering command: /usr/bin/curl curl -sL REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
