feat: implement instant markdown editing support - Issue #133

* Add --edit flag to md-render command enabling client-side editing
* Add --editor-theme and --keyboard-shortcuts options
* Implement comprehensive MarkitectEditor JavaScript class
* Add floating header with change tracking and save functionality
* Support section-based editing with live preview comparison
* Include CSS styling for editing interface components
* Maintain full backward compatibility without --edit flag
* Add extensive test coverage (45 tests across 3 test files)
* Support all template types: basic, github, academic, dark
* Enable responsive design and mobile compatibility
