Note

Add a short UUID suffix to the default RFT output model name and export the helper.

• RFT output model naming:
  • Update build_default_output_model to append a 4-char UUID suffix (via uuid.uuid4()) to "{base}-rft-..." to avoid name collisions.
• Exports:
  • Add build_default_output_model and _map_api_host_to_app_host to __all__.
• Misc:
  • Import uuid.

Bug: UUID Truncation: A Collision Course

Taking only the first 4 characters from uuid.uuid4() provides only 65,536 possible values (16^4), which creates a high collision risk. The birthday paradox means collisions become likely after just a few hundred model creations, reintroducing the "output model exists" errors this change aims to prevent. Using uuid.uuid4().hex[:8] or the full hex would provide better uniqueness.
