New theme: "Aliki"

[st0012]

This theme's "backend" (Ruby part) is mostly based on Darkfish. But design and frontend features is (IMO) a lot better than it.

The work was assisted by Claude Code and Codex through a few days. I cleaned up the history because they're not helping reviewing anyway.

(Aliki is the name of my cat, which was not involved in this work)

Key features

• 3 column design (which matches most API docs nowadays)
• Switchable dark mode
• Right ToC column
• Better search UI
• Slightly better mobile design

Future work

• Configurable top navbar items (at least link to GH and gem?)
• Configurable footer (same as the above?)
• Better social media preview
• ???
