Includes a blog system which fetches whitewind blog posts stored on an
ATProto PDS:
* Optional feature to enable the blog system
* Updated build script to generate client from lexicons
* Fetching system along with in-memory caching and data validation
Finally implemented the actual portfolio design! This includes a tab
mechanism for various aspects of the portfolio and the complete content
for the about tab.
Also fixes the TUI not being correctly scaled due to crossterm using the
dimensions of the server console tty instead of the client pty by
defining a custom `Backend` for ratatui.
