[Bug]: Follow change request templates ignores GitLab and Azure DevOps templates

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/server

Steps to reproduce

1. Use a project hosted on GitLab or Azure DevOps.
2. Commit a template to the repository’s default branch:
   • GitLab: .gitlab/merge_request_templates/Default.md
   • Azure DevOps: .azuredevops/pull_request_template.md
3. Give the template distinctive headings, such as ## Context and ## Verification.
4. Enable Settings → Source Control → Follow change request templates.
5. Create a pull request or merge request through T3 Code’s Git actions.

Expected behavior

When enabled, the setting discovers the hosting provider’s repository template and uses it to generate the description.

Actual behavior

Template discovery is explicitly restricted to GitHub. GitLab and Azure DevOps templates are not passed to the description generator, regardless of the setting.

GitManager.ts:2023 checks provider.kind === "github" before calling detectPrTemplate. The detector in PrTemplateDetection.ts only includes GitHub-compatible paths.
