SDK-hosted sessions can now upload attachments, with a clearer message when files stay local.

What

Attachment uploads used to work only through the local REPL connection. Sessions hosted by the SDK can now upload too, behind the tengu_async_goblet flag (defaults on when the server says nothing). When output is being rendered locally and files could not be delivered, the model is now told the files are only visible in the desktop app on this machine instead of the generic "could NOT be delivered" wording.

Details
  • Upload routing is now a named lane rather than a yes/no: repl, env_brief_upload, env_ccr, env_byoc, sdk_hosted, sdk_hosted_disabled or none.
  • With the flag off, the lane becomes sdk_hosted_disabled and the upload does not happen.
