feat: Add org-appear and enable org emphasis renderingHEADmain

Changes:
- Added org-appear package to show emphasis markers only when editing
- Changed org-fontify-emphasized-text from nil to t to render bold/italic
- Updated comment for org-hide-emphasis-markers to reference org-appear
- org-appear reveals markers (* / _) only when cursor is on them
- Also shows link markup and sub/superscripts when editing
- Updated todo.org to mark org-appear task as DONE (Method 2: 3/5)

Result: Cleaner org-mode editing experience with visual emphasis while
maintaining clean appearance when not editing.
