collections._publicationUrl was never set, so every pubUrl guard in
handleCreate/handleAnnounce evaluated to undefined:
- Reply notifications were never created (if pubUrl && ...) always false
- Boost notifications for our content never created
- Replies from non-followed accounts never stored in ap_timeline
Fix A: set collections._publicationUrl = publicationUrl before
registerInboxListeners() in federation-setup.js.
Fix B: in handleCreate, add an else-if branch that stores replies to
our own posts in ap_timeline even when the sender is not in ap_following,
so they appear in Mastodon client conversation/notification views.
