Add easterEggUtil with generateHappy() function (fix color CSS bug)

[Copilot]

Implements generateHappy() function to display encouraging developer messages in the console. The issue code contained a malformed CSS color value team-layer/kr-corekit#333 (likely from a GitHub reference copy/paste) that should be #333.

Changes

• New utility: package/easterEggUtil/generateHappy/

  • Outputs styled console messages with timestamps
  • 10 default motivational messages with random selection
  • Accepts optional custom message parameter
  • Fixed CSS color from team-layer/kr-corekit#333 → #333

• Exports: Added easterEggUtil to package exports (package.json, package/index.ts)

• Tests: 6 test cases covering default/custom messages, console output formatting, and styling parameters

  • Improved test assertions to avoid duplication (based on code review feedback)

• Documentation: Comprehensive README documentation

  • Individual README.md in package/easterEggUtil/generateHappy/ with usage examples, API details, and feature descriptions
  • Updated main README.md with easterEggUtil examples, tree-shaking imports, and API reference

Usage

import { generateHappy } from 'kr-corekit';

generateHappy(); // Random encouraging message
generateHappy('Custom message! 🎉'); // Custom message

Console output:

[5:28:35 AM] Progress, not perfection. 🚀
