Summary

Adds an opt-in one-way ActivityPub publisher so Rontal-powered blogs can be followed from Mastodon and other fediverse clients.

Federation is off by default. Enable it in config/rontal.ts:

fediverse: {
  enabled: true,
  username: 'blog',
  public_base_url: 'https://blog.example.com',
  post_permalink: 'https://blog.example.com/posts/{slug}', // optional
}

What this includes

WebFinger at /.well-known/webfinger
Actor (Service) at /ap/actor with auto-generated RSA keypair
Outbox of Create activities for published posts
Inbox accepting signed Follow / Undo(Follow) (other activities ignored)
Fan-out of signed Create / Update / Delete on publish / update / unpublish / delete
Migrations for fediverse_actor_keys and fediverse_followers
Docs + tests (40 passing)

Out of scope (by design)

Replies, likes, boosts, and other two-way social features — this is publish-only.
