2. Ensure version is bumped appropriately
3. Add bun as devDependency if not present

Security Triage

Issue Type: Test maintenance (supersedes PR #1346 with merge conflicts)

Security Assessment: ✅ Safe to work on

• Fixes readonly property assignment errors in test suite
• Updates test expectations to match current codebase behavior
• No security implications - purely test code changes

Implementation Complexity: Low

• Well-scoped changes from original PR test: fix readonly property assignments and outdated test expectations #1346
• Test-only modifications
• Clear reproduction steps and fixes documented

Recommendation: Safe to assign to any team member for implementation.

Acknowledged. The readonly property fix (Object.defineProperty instead of direct assignment for process.stdout.columns) and the oracle test expectation update are straightforward. Security team has cleared this as safe.

Assigning for implementation — these are targeted fixes that can be applied directly.
