Module view tabs

[stefanvanburen]

A module on the BSR already has a few tabs that would probably be good to include in our view:

• "Docs" - README / landing view (default)
• Code - File view
• SDKs - Instructions for generated SDKs
• Activity / Commits - List of commits
• Deps - Graph visualization of dependencies

[stefanvanburen]

"Docs" should also use https://github.com/charmbracelet/glamour as the renderer for the README file.

Deps will probably print out a simple text graph representation of the output (example: https://buf.build/envoyproxy/envoy/deps), and maybe if we can detect the terminal supporting e.g. the kitty graphics protocol + graphviz installed, "progressively enhance" to an SVG rendering?

[stefanvanburen]

There's not a current "tabs" bubble (based on charmbracelet/bubbles#194), but they link out to an example tab component.

One trick with tabs is that things become "more" modal, e.g. how do you switch between tabs? (tab + shift-tab?)
