v0.9.0

Added

• Photos and files, kept in your own Cloudflare R2 bucket (private; every
  link is signed and expires). Both are off by default and turned on
  separately, in Settings → Advanced → Photos and files or with the new
  helppuff files command:
  • In the chat (files.chat): visitors send photos and PDFs with a
    paperclip next to the message box, only while a person has the chat
    (live, the usual choice) or any time (always). Photos are made smaller
    in the browser and lose their location data. The team sees them in the
    conversation and the live chat, and as links on Telegram. The assistant
    is told a file arrived but never opens it, unless the assistant sees
    photos is on: then a Workers AI vision model (Llama 4 Scout by default)
    describes each photo once and the assistant reads that.
  • On jobs (files.jobs): a Files section on every job (drop or attach
    photos, PDFs, Office documents, text, CSV, MP4/MOV), with the photos the
    visitor sent in the job's conversation. Members attach and remove their
    own. helppuff jobs attach|files|detach, and GET/POST /jobs/:id/files,
    DELETE /jobs/:id/files/:fileId in the API.
  • Limits on Settings → Advanced and in helppuff.json: the largest file
    from visitors and on jobs, files per chat, how long chat files are kept
    (90 days; job files stay until removed), and
    security.limits.uploadsPerIpPerHour.
• helppuff deploy makes the R2 bucket (knowtific-helppuff-<site>) whenever
  the Cloudflare account has R2 on, so turning files on needs no redeploy.
  Without R2 the deploy goes on, and says how to turn it on only when files
  are on. helppuff doctor checks it.

Upgrading

• Run helppuff upgrade: it adds the files table to the database and makes
  the bucket. To use files, R2 must be turned on once for the Cloudflare
  account (the dashboard asks a person to accept the plan, free up to 10 GB).
  An API token (instead of wrangler login) needs Workers R2 Storage ›
  Edit too.
