feat: comprehensive Chrome extension system enhancements

Phase 2 Complete: Upgraded extension management with real implementations

✅ Replaced Demo Extensions with Real Sources:
- axe-devtools: GitHub dequelabs/axe-devtools-html-api
- colorzilla: CRX + GitHub fallback (bhlhnicpbhignbdhedgjhgdocnmhomnp)
- json-viewer: GitHub tulios/json-viewer
- web-developer: CRX + GitHub chrispederick/web-developer
- whatfont: CRX + GitHub chengyinliu/WhatFont-Bookmarklet

✅ Expanded Extension Catalog (9 → 15 extensions):
- ublock-origin: GitHub gorhill/uBlock (ad blocker)
- octotree: CRX + GitHub ovity/octotree (GitHub code tree)
- grammarly: CRX kbfnbcaeplbcioakkpcpgfkobkghlken
- lastpass: CRX hdokiejnpimakedhajhdlcegeplioahd
- metamask: GitHub MetaMask/metamask-extension
- postman: CRX fhbjgbiflinjbdggehcddcbncdddomop

✅ Enhanced Extension Architecture:
- Updated TypeScript interfaces for flexible source types
- Added CRX + GitHub fallback support for robust installation
- Created extension-specific visual indicators and scripts
- Enhanced popup HTML generation with proper color themes

Benefits: 67% more extensions, real functionality vs demos, robust fallback system
