feat(ci): add Automate Issue Assignment with /claim Command

[khedkaravani-rgb]

User description

Summary

Implemented a GitHub Actions workflow that allows contributors to claim unassigned issues by commenting /claim.

The workflow:

• Detects /claim comments on issues.
• Supports case-insensitive commands such as /claim, /Claim, and /CLAIM.
• Automatically assigns the issue to the commenter.
• Adds the assigned label.
• Posts a confirmation comment after a successful claim.
• Prevents already-assigned issues from being reassigned.
• Uses issue-level concurrency to prevent race conditions when multiple contributors claim the same issue.
• Includes error handling for failed assignment attempts.
• Uses minimal GitHub Actions permissions.
• Ignores pull-request comments and unrelated comments.

The issue-claiming process is also documented in CONTRIBUTING.md.

📝 Walkthrough

Walkthrough

Adds a GitHub Actions workflow that processes /claim issue comments, assigns eligible contributors, adds an assigned label, prevents concurrent claims, and reports results. Updates CONTRIBUTING.md with claim instructions and restrictions.

Changes

Issue Claiming

Layer / File(s)	Summary
Claim command automation and guidance .github/workflows/claim-issue.yml, CONTRIBUTING.md	The workflow validates issue comments, ignores pull requests and invalid commands, serializes claims, assigns the commenter, adds the assigned label, and posts success or failure comments. The contribution guide documents the command and claim conditions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 5355c

A /claim request can assign an issue successfully while failing to add the assigned label or confirmation message, leaving the issue in an inconsistent state and reporting the wrong failure. This bounded correctness issue should be fixed before merge.

errors. After addAssignees succeeds, handle label creation and
confirmation-comment failures as finalization failures, retrying or repairing
the assigned label as needed without reporting that assignment failed; preserve
