Complete JavaScript integration Phase 3 and comprehensive review

Browse Source 
This commit completes Phase 3 (Event System) and includes a thorough
midpoint review that identified and fixed critical gaps from earlier phases.

Major accomplishments:
• Complete event system with addEventListener/removeEventListener API
• Event dispatch system with preventDefault/stopPropagation support
• Click event integration with w3m's existing mouse handling system
• Enhanced document.write() from stub to functional implementation
• Fixed critical anchor-DOM integration gap from Phase 2
• Comprehensive code review and stub elimination
• Full DOM element extraction and JavaScript object conversion
• Working noscript tag suppression when JavaScript is enabled

Testing verified:
• JavaScript execution and DOM manipulation working correctly
• document.write() creates DOM elements and displays content properly
• noscript content correctly hidden when JavaScript is enabled
• Click events integrate properly with w3m's mouse system
• No compilation errors or warnings (except minor unused variable)

Phase status: Phases 1-3 now complete and fully functional.
Remaining stubs are safe and won't cause unexpected behavior.
