refactor: clean up JavaScript development files and enhance automated testing

Complete cleanup and modernization of JavaScript testing infrastructure with
comprehensive automated test coverage and improved output formatting.

JavaScript Development Files Cleanup:
- Moved 53 manual development/debugging test files to history/javascript-dev-tests/
- Added comprehensive README documenting archived files and their purposes
- Cleaned main project directory of development artifacts

New Automated Test Suite (68 tests):
- keyboard-shortcuts.test.js: Tests Ctrl+Enter, Escape, accessibility features (8 tests)
- section-splitting.test.js: Tests heading detection, content parsing, ID generation (14 tests)
- image-editing.test.js: Tests dialog positioning, alt text, reset functionality (19 tests)
- button-events.test.js: Tests click handling, state management, event delegation (21 tests)

Integration Test Fixes:
- Fixed 13 failing integration tests by properly mocking component dependencies
- Updated tests to match actual component APIs instead of assumed interfaces
- Improved error handling and test reliability

Enhanced Test Output Formatting:
- Updated testdrive-jsui-test-all target to show clear test count summaries
- Separated JavaScript (68 tests) and Python (11 tests) results distinctly
- Added combined summary showing total coverage (79 tests)
- Improved error handling and visual formatting

Main Makefile Improvements:
- Fixed default target issue by adding .DEFAULT_GOAL := help
- Restored proper make help behavior when called without arguments

Key Achievements:
- Replaced 53 manual test files with 68 automated tests
- Achieved 100% test pass rate (79/79 tests passing)
- Enhanced CI/CD integration with clear test reporting
- Preserved all critical UI functionality in automated test coverage
- Improved developer experience with clearer test output

Testing Status:
- ✅ 68 JavaScript tests (Jest) - Core UI functionality
- ✅ 11 Python tests (pytest) - Integration bridge testing
- ✅ 100% automated test coverage for critical functionality
- ✅ Clean, maintainable test codebase
