andros 349a5e1376 Add ActivityPub and RSS bridges serving virtual social.org feeds
Expose external accounts as virtual Org Social feeds that any client
can follow with a plain #+FOLLOW: line:

- /bridge/activitypub/@{user}@{instance}/ bridges a Mastodon or any
  ActivityPub account (WebFinger, actor and paginated outbox; only
  public top-level notes, with CW, hashtags, language and attachments)
- /bridge/rss/?url={feed} bridges any RSS/Atom feed (entry title as
  *** sub-heading, converted body and link to the original article)

Registration is implicit on first GET. Bridged data is stored in the
existing Profile/Post tables so /profile/, /search/ and the rest of
the API work on bridged feeds. Active bridges are refreshed every 15
minutes; bridges unrequested for 90 days are cleaned up.

Remote HTML is converted to Org text, escaping headline-like lines so
external content cannot inject posts. Fetches enforce the Webmention
SSRF protections, a 10s timeout and a 5MB size cap. Bridged posts
never queue Webmentions nor publish notifications.
