feat(treewide): Prepare for first release

This commit contains many changes, as they were developed alongside
`git-bug-rs` and unfortunately not separately committed.

A toplevel summary would include:
- Appropriate redirects,
- The templating moved to `vy` (as this works with rustfmt formatting),
- Search support (via `git-bug-rs`),
- And better layout in the link section.
