feat: Add unified language detector for code analysis
- Created LanguageDetector class supporting 20+ programming languages - Confidence-based detection with customizable thresholds (min_confidence parameter) - Replaces duplicate language detection code in doc_scraper and pdf_extractor - Comprehensive test suite with 100+ test cases Changes: - NEW: src/skill_seekers/cli/language_detector.py (17 KB) - Unified detector with pattern matching for 20+ languages - Confidence scoring (0.0-1.0 scale) - Supports: Python, JavaScript, TypeScript, Java, C++, C#, Go, Rust, PHP, Ruby, Swift, Kotlin, Shell, SQL, HTML, CSS, JSON, YAML, XML, and more - NEW: tests/test_language_detector.py (20 KB) - 100+ test cases covering all supported languages - Edge case testing (mixed code, low confidence, etc.) - MODIFIED: src/skill_seekers/cli/doc_scraper.py - Removed 80+ lines of duplicate detection code - Now uses shared LanguageDetector instance - MODIFIED: src/skill_seekers/cli/pdf_extractor_poc.py - Removed 130+ lines of duplicate detection code - Now uses shared LanguageDetector instance - MODIFIED: tests/test_pdf_extractor.py - Fixed imports to use proper package paths - Added manual detector initialization in test setup Benefits: - DRY: Single source of truth for language detection - Maintainability: Add new languages in one place - Consistency: Same detection logic across all scrapers - Testability: Comprehensive test coverage - Extensibility: Easy to add new languages or improve patterns Addresses technical debt from having duplicate detection logic in multiple files.
