Implement the avatar and a preflight dry run
The avatar is now applied rather than deferred: BotFather's /setuserpic is a conversation in which you send a photo, so the file is uploaded and sent as a message. It is content addressed -- replacing the file is what triggers an update, and the digest is recorded only after BotFather confirms, so a failed upload retries rather than being remembered as done. The image is validated before the conversation starts, because an image rejected halfway leaves the bot registered without a picture. Adds `provision preflight`: spec, avatar, OpenBao reachability, credentials, session presence, salt and the resulting plan, checked in one run that writes nothing and never contacts Telegram. Every failure it reports is one that would otherwise surface after a phone number had been spent. Two bugs it found immediately. The avatar path is documented as repo-relative but resolved against the spec's own directory, so the real campaign spec failed to find its own asset. And the OpenBao error named both variables when only one was missing, sending the reader to check the one already set.

referenced but absent, and `apply` will fail on `/setuserpic` until it exists.

It is left for a person on purpose — it is the first thing a stranger sees of

HelixForge on Telegram, and a generated placeholder would quietly become

permanent.

PNG, dimensions, size, and a content digest so replacing the file is what

triggers an update.
