Hiroba v0.3.2

Desktop installers for Hiroba v0.3.2.

After installing, open an invite link or point the app at your server.
Server self-hosting: docs/SELF_HOSTING.md

What's Changed

• Invites are taken on the invite page: open the link, sign in with Google, GitHub or an e-mail code, and you are a member. "Open in Hiroba" then signs the app in directly through a one-time hiroba://auth/<code> link, so the app no longer has an invite field and there is nothing to paste after installing.
• The org-setup step points invitees to their invite link instead of asking for a code, and closes by itself once they have joined.
