- Update E2E tests to expect "Clone Detection Analysis Report" instead of "Clone Detection Results"
- Update E2E tests to expect "Dead Code Analysis Report" instead of "Dead Code Detection Results"
- Update severity expectations from "CRITICAL" to "High" in dead code tests

- Update all references from pyqol and pyscan to pyscn
- Rename directories: cmd/pyqol → cmd/pyscn, python/src/pyscan → python/src/pyscn
- Update Go module path to github.com/ludo-technologies/pyscn
- Update PyPI package name to pyscn
- Update all documentation and configuration files
- Successfully published to PyPI as pyscn
This change provides a shorter, more memorable package name (5 characters)
that is easier to type in commands like 'pyscn analyze' while maintaining
the core meaning of Python code scanning/analysis.
Remove all progress reporting infrastructure from the codebase as it was
architectural debt that provided misleading feedback to users. Progress
bars were tracking file parsing (fast O(n) operation) instead of actual
computation-intensive algorithms like clone detection (O(n²)).
Major changes:
- Remove ProgressReporter interface from domain layer
- Delete service/progress_reporter.go and all implementations
- Update all service classes to remove progress fields and parameters
- Update all use case classes and builders to remove progress dependencies
- Clean up all command layer progress reporter creation
- Fix all test files to remove progress-related mock objects and assertions
- Remove progress parameters from 25+ files across the codebase
This simplifies the architecture and removes complexity without losing
any meaningful functionality. Future progress reporting should target
the actual heavy computational algorithms, not file I/O operations.
All tests pass and build succeeds after this comprehensive refactoring.

Updated TestComplexityCleanCancellation to use errors.Is() for
checking context.Canceled in error chain, properly handling
wrapped errors from the service layer.

## Input Validation Improvements
- Add input validation to CloneService.ComputeSimilarity with empty fragment checks, size limits (1MB), and nil context validation
- Add validation to DetectClones and DetectClonesInFiles methods with comprehensive parameter checks
- Add nil checks to all APTED tree operations (ComputeSimilarity, computeApproximateDistance)
- Add parser result validation with nil checks for AST nodes and parse results
## Configuration Consolidation
- Create unified CloneConfig structure with logical sections (Analysis, Thresholds, Filtering, Input, Output, Performance)
- Centralize clone type thresholds (0.95, 0.85, 0.70, 0.60) into constants package
- Add comprehensive validation for all configuration sections with detailed error messages
- Maintain backward compatibility through adapter functions
## Memory Management Enhancements

- Add priority queue-based filtering for large datasets with early similarity filtering
- Implement recursive depth limits (1000 levels) to prevent stack overflow in tree operations
## Test Coverage
- Add comprehensive validation tests for all service methods

This comprehensive implementation replaces placeholder code with a fully
functional clone detection system using the APTED (All Path Tree Edit Distance)
algorithm for Python code analysis.
## Major Features Added
### 🔬 APTED Algorithm Implementation
- Core APTED algorithm with tree edit distance calculation
- Configurable cost models for insert, delete, and rename operations
- Optimized performance: <1s for 1000-node trees (was 26.6s)
- Support for all clone types (Type-1 through Type-4)
### 🏗️ Complete Architecture
- Domain layer with clean interfaces and validation
- Service layer with proper error handling
- CLI integration with comprehensive options
- Configuration system supporting YAML/JSON
- Output formatters for JSON, YAML, CSV, and text
### 🐍 Python AST Integration
- Tree-sitter Python parser integration
- AST to tree node conversion for APTED
- Proper handling of Python syntax constructs
- Support for functions, classes, and complex expressions
## Key Bug Fixes
### ❌ Replaced Magic Number 0.7
**Before**: `return 0.7, nil // placeholder`
**After**: Full APTED-based similarity calculation with real parsing
### 🔧 Fixed All TODO Items
- **complexity_reporter.go:171**: Use version package instead of hardcoded "dev"
- **complexity_reporter.go:173**: Track actual file count vs hardcoded 1
