Major documentation overhaul to ensure nothing is lost and provide clear guidance
for all future development sessions.

New Files:
- docs/roadmap/CLAUDE-CONTEXT.md - North star document for development
  - Living document updated every session
  - Tracks WHERE WE ARE, WHERE WE'RE GOING, WHAT TO DO NOW
  - Provides breadcrumbs and context for future Claude sessions
  - Quick reference links to all key files
  - Lessons learned and development principles

Enhanced Files:
- v2.5.0-TEMPLATES-AND-FEATURES.md - Comprehensive v2.5.0 specification
  - Added prioritization matrix (9 features ranked)
  - Added detailed user stories (10 stories)
  - Added architecture decisions (Visual Builder, Mobile, Templates)

 ## What is AgentCodeX?
 
 AgentCodeX is a self-improving agentic development framework that uses 23 specialized AI agents to build production-ready applications from ideation. This is the **framework itself**, not a project built with AgentCodeX.
 
 **Key Distinction:** You are working on the framework that enables other Claude Code instances to build applications autonomously. Changes here affect all projects created with AgentCodeX.
 
+**Current Version:** v2.4.2 (Released October 13, 2025)
+**Latest Achievement:** MCP-First Architecture (all data via JSON-RPC 2.0 servers)
+**Next Milestone:** v2.5.0 Visual Builder (Web-based project generator)
+
