Overview

Adds an experimental llama.cpp backend for promptable apps, lets an app declare the environment variables it cannot run without, and updates mmif-python to 1.8.1.

Additions

• ClamsGGUFPromptableApp (experimental): a promptable app base class that runs a pinned GGUF model in its own llama-server process, without torch. Needs the new [llamaserver] extra and a llama-server executable. See "HF and GGUF Promptable Apps" in the documentation for how it differs from ClamsHFPromptableApp (Helper module/class for LLM-based apps #263).
• clams-python-llamaserver container image, built on llama.cpp's CUDA server image.
• RESTIFIER_PRODUCTION_WORKERS and RESTIFIER_PRODUCTION_MAX_REQUESTS: optional app class attributes for the gunicorn worker count and recycling in production mode.
• env_requirements: app metadata field listing the environment variables an app cannot run without; the app stops at startup if any is unset (When an environment variable is need to run an app #304).

Changes

• mmif-python is updated to 1.8.1.
