Subject: [PATCH] feat(ci): add Claude automated bug fixer workflow

Adds a GitHub Actions workflow that triggers when an issue is labeled
"bug". Claude analyzes the issue, implements a targeted fix, and opens
a draft PR linking back to the original issue.

+            A bug has been reported in issue #${{ github.event.issue.number }}.
+
+            Issue title: ${{ github.event.issue.title }}
+            Issue body:
+            ${{ github.event.issue.body }}
+
+            Please do the following:
+            1. Analyze the issue carefully to understand the bug being reported.
+            2. Explore the codebase to find the relevant code that is likely causing the bug.
+            3. Implement a fix for the bug.
+            4. Create a new branch named `fix/issue-${{ github.event.issue.number }}` from main.
+            5. Commit your changes to that branch with a descriptive commit message.
+            6. Open a **draft** pull request targeting the main branch with:
+               - A clear title summarizing the fix
+               - A description explaining what the bug was and how you fixed it
+               - `Fixes #${{ github.event.issue.number }}` in the PR body
+
+            Important guidelines:
+            - Only change code that is directly related to fixing the reported bug. Do not refactor or make unrelated improvements.
+            - If you cannot determine the root cause or the fix is too risky/complex, leave a comment on the issue explaining what you found and why an automated fix isn't appropriate.
+            - Make sure the fix is complete and the code compiles/passes linting before opening the PR.
