Sync from GitHub main: v0.1.1, v0.1.2, wiki sync

Squashes the work that landed on GitHub via PRs #2 (v0.1.1), #3
(v0.1.2), and #4 (wiki sync) into a single commit on Gitea so both
remotes converge. Content is identical to github/main; commit history
is split for branching reasons (Gitea was merged via PR #1 long ago,
GitHub used squash merges from then on, so the SHAs diverged).
