Repository Restructuring: Implement 3-Tier Version System 🎯

This commit implements the complete repository restructuring with clear
version semantics and branch organization.

## Branch Structure (NEW)

main  (1.0)   → QuantCoder 1.0 - Stable production (quantcli)
beta  (1.1)   → QuantCoder 1.1 - Improved legacy (quantcli, testing)
gamma (2.0)   → QuantCoder 2.0 - Complete rewrite (quantcoder, alpha)

## Version Changes

- Renamed branch: claude/refactor-quantcoder-cli-JwrsM → gamma
- Version renumbering: v4.0 → 2.0.0-alpha.1
- Clear progression path: 1.0 → 1.1 → 2.0

## Files Changed

### Version Updates
- quantcoder/__init__.py: Updated to 2.0.0-alpha.1
- docs/NEW_FEATURES_V4.md: Updated all version references
- README.md: Added version badges and branch navigation

### New Documentation
- docs/VERSION_COMPARISON.md (NEW)
  * Complete version comparison guide
  * Feature matrix (1.0 vs 1.1 vs 2.0)
  * Migration guides
  * Decision tree for choosing version
  * Performance and cost estimates

- docs/BRANCH_VERSION_MAP.md (UPDATED)
  * Reflects new 3-tier structure
  * Detailed branch information
  * Clear selection guide
  * Restructuring summary

## Key Benefits

✅ Clear version semantics (1.x = legacy, 2.x = rewrite)
✅ Proper semantic versioning
✅ Easy branch selection for users
✅ Clean repository (3 active branches)
✅ Logical progression path

## For Users

Stable Production? → main (1.0)
Improved Legacy?  → beta (1.1)
Cutting Edge?     → gamma (2.0) ⭐

## Breaking Changes

NONE - This is organizational only. All code remains functional.

## Next Steps

- Rename refactor/modernize-2025 → beta (requires admin access)
- Archive feature branches (tag then delete)
- Update GitHub branch settings
- Announce restructuring to users

 QuantCoder is a command-line tool that allows users to generate QuantConnect trading algorithms from research articles using natural language processing and large language models (LLMs). It was initiated in November 2023 and based on a cognitive architecture inspired by the article ["Dual Agent Chatbots and Expert Systems Design"](https://towardsdev.com/dual-agent-chatbots-and-expert-systems-design-25e2cba434e9)
 
 The initial version successfully coded a blended momentum and mean-reversion strategy as described in ["Outperforming the Market (1000% in 10 years)"](https://medium.com/coinmonks/how-to-outperform-the-market-fe151b944c77?sk=7066045abe12d5cf88c7edc80ec2679c), which received over 10,000 impressions on LinkedIn.
