v2.0.0 - SCIP Architecture Migration

🚀 Major Changes

Complete architectural overhaul - This release represents a fundamental redesign of the code indexing system.

New Architecture

• Three-layer service architecture: Service → Tool → Technical Components
• Unified SCIP indexing: Replace language-specific analyzers with SCIP protobuf format
• Simplified codebase: Reduced from 40K+ to ~1K lines of core logic

Performance & Reliability

• Faster indexing: Tree-sitter AST parsing instead of regex-based analysis
• Better accuracy: SCIP provides more precise code intelligence
• Reduced memory usage: Streamlined data structures and processing

Backward Compatibility

• MCP API unchanged: All existing MCP tools work without modification
• Automatic migration: Legacy indexes are automatically migrated
• Same functionality: All user-facing features preserved

🔧 Technical Details

Removed Components

• Language-specific analyzers (C, C++, Java, JavaScript, Python, etc.)
• Legacy indexing models and relationship management
• Complex duplicate detection and qualified name systems

New Components

• SCIP-based unified indexing system
• Service-oriented business logic layer
• Composable technical tool layer

📦 Migration

Existing users can upgrade seamlessly - the system will automatically:

1. Detect legacy index format
2. Migrate to new SCIP format
3. Maintain all existing functionality
