feat: Add native Git commit linking and keyword status triggers to DevTrack issues (#2663)

[Neelr1912]

Problem Statement

Previously, developers had to manually update DevTrack issues to match their Git commits or pull request progress, which was time-consuming and often resulted in tracking boards getting out of sync with codebases.

Solution

We have introduced a native Git integration that parses commit messages from linked GitHub and GitLab repositories to automatically link commits to referenced issues and update their statuses based on configured triggers.

Key Changes

1. Core Parser & Logic (src/lib/git-commit-linking.ts):

   • Implemented a protocol-agnostic URL normalizer (normalizeRepoUrl) to match repository links.
   • Built a commit message regex parser that extracts issue references (e.g. DT-402) and optional trigger keywords.
   • Handled duplicate commit associations gracefully and added idempotency guards so identical webhook events do not log repeated activities.

2. Keyword Triggers & Status Transitions:

   • Matches standard closing keywords (e.g., Fixes, Resolves, Closes) to transition issues to the Done column.
   • Matches review keywords (e.g., Review, In-Review) to transition issues to the In Review column.
   • Logs status transitions and commit details directly into the devtrack_issue_activities timeline.

3. Webhook Subsystems:

   • Integrated commit checking directly into the GitHub push webhook handler (src/app/api/webhooks/github/route.ts).
   • Created a brand-new webhook endpoint for GitLab (src/app/api/webhooks/gitlab/route.ts) supporting verification via token headers.

4. Project Settings Management UI (src/app/dashboard/settings/page.tsx):

   • Added a DevTrack Projects settings section to link and unlink Git repositories.
   • Implemented toggles to enable or disable keyword triggers per project.
   • Included clear visual setup instructions for configuring repository webhooks in GitHub/GitLab.

5. Project API (src/app/api/projects/[id]/route.ts):

   • Added a PATCH handler to allow updating project settings on the server side.

Verification

• Dependencies installed and workspace builds correctly.
• TypeScript compiler compilation check verified successfully:

  npx tsc --noEmit

Hi @Neelr1912 — thanks for the PR! 🙌

DevTrack asks contributors to ⭐ star the repo before a PR can be merged. It takes two seconds and is the easiest way to support the project.
