Cookbook/Dependencies recipes: install into configured venv, drop 'uv venv'

Recipes now hold ONLY the install command(s). The rendered <pre>
prepends a 'source <envPath>/bin/activate' line so the user sees a
paste-ready sequence; Run uses env_prefix (same path the Install
button uses) to activate the configured venv before the install
command, so the install lands in the existing environment rather
than a fresh .venv in whatever CWD the tmux task happens to start in.

- cookbook-deps-recipes.js: trim each recipe to its single pip command
- cookbook.js: _recipeDisplayText() prepends the activate context for
  display; pre's data-dep-recipe-install holds the raw install-only
  command list so Run knows what to send; Run builds env_prefix the
  same way _installDep does.
