v0.5.0

Added

• Facebook is a channel like the others. The Facebook card on Channels
  connects a page in one press — the browser leaves for Chatfuel's page, you
  sign in to Facebook, pick the page, and come back with it connected — and
  offers Refresh access once the bot has one. A link deals in one page, so a
  bot that already has two or more (connected in the Chatfuel dashboard) keeps
  Disconnect per page and no link.
• Messenger in the inbox reads the whole conversation. A comment shows the
  page post it was left on, with its text, picture and link; a button the
  contact tapped and an m.me link they opened are their own rows, the ref
  included; a message that came from a Click-to-Messenger ad says which ad; and
  a contact the page may not write to first says so on the contact card.
• Facebook flows have a block of their own: Human agent (Facebook), created
  on the canvas or added inside a block, like the other four platforms'.
• The Facebook post picker refreshes from Facebook, and waits for the new
  posts to land before it re-reads.
• Test comment replies. On Instagram · Posts & Reels and Facebook · Post
  comments the AI Agent's test panel is a post — one the automation watches,
  drawn at random — with a comment field. Leave a comment and the automation
  answers it the way it answers a real one: the public reply shows under your
  comment, and when it also writes in the DM, Test DMs opens that conversation
  to carry on. Restart tries again on a fresh post.
• Pick the AI model the bot answers with. The AI Agent's Default · All
  channels page has an AI model card: every model the bot may use, with its
  input and output price per million tokens, the one in use marked. It is one
  setting for the whole bot, changed with the Configure · Edit permission, and
  going back to the default follows the default rather than pinning it.
