Cookbook/Dependencies: Pip/uv vs Docker variant toggle on recipe panel

Each recipe catalog entry now carries two variants:
  variants.pip    → uv pip install …
  variants.docker → docker pull <image>

A small 'Install via' pill row in the panel toggles between them
(default = Pip/uv per the user's preference). Switching variant or
changing the model re-renders the <pre> via _refreshRecipePre(); the
display text drops the 'source venv/bin/activate' prefix for Docker
since docker pull doesn't need a venv. Run honours the active variant
so picking Docker queues 'docker pull …' as the tmux task.
