Refactors site to use interactive terminal UI

Moves site from static HTML to a dynamic terminal interface.

This commit represents a major overhaul, introducing:
- A functional terminal emulator implemented in JavaScript.
- Command parsing and execution framework.
- Various terminal commands for navigation and utility functions.
- SASS conversion.

The old CSS and simple HTML are completely removed. A new Hugo theme is implemented.
