Description

This PR removes all direct usages of System.out and printStackTrace() to align the codebase with SonarQube rules:

• S106: Avoid using System.out or System.err
• S1148: Avoid using printStackTrace()

All such occurrences have been replaced with appropriate logger.debug() or logger.error() statements while maintaining existing logging behavior (especially within prettyPrint helpers).

Additionally:

• IDE-specific suppression comments were replaced with standard @SuppressWarnings annotations.
• Test classes intentionally retain System.out usage for debugging convenience.
• No functional or behavioral changes introduced.

Fixes: none (code quality cleanup)

---

Type of Change

• 🐛 Bug fix
• ✨ New feature
• ♻️ Refactor (non-breaking change)
• 🧪 Tests
• 📝 Documentation
• 🧹 Chore (build or tooling)

Checklist

• I have verified the build passes successfully
• I have ensured no logic or functional behavior changed
• The PR title is descriptive and follows commit conventions
• The code adheres to Sonar recommendations (S106, S1148)
• All tests pass locally

Screenshots / Additional Context

No visual changes — this is a pure code hygiene and Sonar alignment cleanup.

@kuntal1461 thank you for your time and contribution. I have some concerns about this PR. In addition to removing unnecessary System.out and printStackTraces, I see other changes that should not be part of this PR. For example, I see changes that are in PR #4986. There's also a configuration for VSCode that should not be added. Please correct this PR.
