Dependency Updates Review

This PR updates major dependencies and Node.js version requirements (Node 20 → Node 22, TypeScript 5.9 → 6.0). The changes are mostly straightforward dependency upgrades.

Critical Issue

One version inconsistency was identified in the GitHub Actions workflows that should be corrected before merge.

Summary of Changes

• Node.js minimum version increased to 22 (drops support for Node 20)
• TypeScript upgraded from 5.9 to 6.0
• ESLint and related plugins updated to latest major versions
• GitHub Actions workflows aligned with Node version changes
• TypeScript config simplified (removed redundant options covered by strict mode)

The changes appear aligned with the stated goal of dependency updates for April 2026.
