Refresh Willow's interface and distribution

[breaking] - The Go module moved from git.sr.ht/~amolith/willow to secluded.site/willow. - Go installations now use secluded.site/willow/cmd/willow.

v0.0.1-alpha1

The most basic features are present and pretty reliable, so I'll start publishing alpha builds for adventurous people. When there are material improvements, I'll use them for at least a few days before publishing a new build. -----BEGIN SSH SIGNATURE----- U1NIU0lHAAAAAQAAAEoAAAAac2stc3NoLWVkMjU1MTlAb3BlbnNzaC5jb20AAAAgzEkAhr f0dc6ZiSJXHc/mDhl7rRRGcNCSuENi7R/pfKkAAAAEc3NoOgAAAANnaXQAAAAAAAAABnNo YTUxMgAAAGcAAAAac2stc3NoLWVkMjU1MTlAb3BlbnNzaC5jb20AAABAUz6paFsqISYvqE /GRJWdTZqYwBn/DYZf3Brs9/xquBp1LUI5eang8o7MiF33TrZDj+tLmfPJQ887tNxzzpSt CwEAABVK -----END SSH SIGNATURE-----
