feat: enhanced status bar with word count, char count, line/col, encoding

- Restructured status bar into left/right sections with separators
- Added character count, cursor line/column position, encoding, and language mode indicators
- Added cursor position tracking via CodeMirror onUpdate callback
- Added file path display that updates on tab switch
- Simplified word count display for cleaner status bar layout
