Add comprehensive test infrastructure

- Created unit tests for BaseScraper with mocking
- Added integration tests for parallel processing
- Created end-to-end tests with realistic mock data
- Fixed initialization order in BaseScraper (logger before user agent)
- Fixed orchestrator method name (archive_current_file)
- Added tenacity dependency for retry logic
- Validated parallel processing performance and overlap detection
- Confirmed spec-compliant markdown formatting in tests

Tests cover:
- Base scraper functionality (state, markdown, retry logic, media downloads)
- Parallel vs sequential execution timing
- Error isolation between scrapers
- Directory structure creation
- State management across runs
- Full workflow with realistic data
