Implement `/assign` Command via GitHub Actions

[Pranjal6955]

Summary

Enable contributors to self-assign issues and pull requests using a simple /assign command, reducing maintainer workload and speeding up task ownership.

---

Contexts

Currently, assigning issues or PRs requires manual action from maintainers, which can slow down collaboration. By implementing a GitHub Action that listens to /assign commands in comments, contributors can take ownership of tasks instantly.

The system should support assigning the commenter or a specified GitHub user, while handling edge cases like invalid usernames, bot comments, and duplicate assignments.

---

Tasks

• Create GitHub Action workflow (.github/workflows/assign.yml)

• Parse /assign command from issue/PR comments

• Implement logic for:

  • /assign → assign commenter
  • /assign @username → assign mentioned user

• Integrate GitHub REST API for assignment

• Add validation (ignore bots, invalid users, duplicates)

• Add confirmation comment after assignment

• (Optional) Restrict usage to contributors/org members

---

Acceptance Criteria

• /assign assigns the commenter correctly
• /assign @username assigns the specified user
• Invalid commands or users are handled gracefully
• No duplicate assignments occur
• Confirmation comment is posted after assignment
• Tests added (if applicable)
• Documentation updated (if needed)
