chore: block compromised npm releases & pin known-good versions (2025-09-08)

Add security measures to prevent malicious package versions:

✅ Added Yarn constraints blocklist (.yarn/constraints.pro)
- Blocks 19 malicious versions of compromised packages
- Prevents installation of known bad releases
- Covers color, chalk, and related dependency chains

✅ Pinned exact safe versions via resolutions (package.json)
- color: 4.2.3 (last known good)
- color-string: 1.9.1 (last known good)
- color-convert: 2.0.1 (last known good)
- color-name: 1.1.4 (last known good)
- chalk: 4.1.2 (last known good)
- Plus 13 additional related packages

✅ Updated Yarn configuration
- Added constraints plugin
- Configured for security enforcement
- Updated lockfile with safe versions

🎯 Security Benefits:
- Prevents qix hack
- Blocks malicious postinstall scripts
- Ensures reproducible, secure builds
- Centralized security policy enforcement
