Allow `abra app new <git-url>` to use a recipe from outside the
catalogue. On clone, a `.abra-source` sidecar records the canonical
host/path name (the on-disk directory escapes "/" and "." lossily), and
IsClean ignores it. When templating the app's .env, a `RECIPE=<canonical
name>` line is injected so a later `abra app deploy`, possibly on another
machine, re-fetches the recipe from the same git source. `recipe ls` now
shows a source column listing these external recipes alongside catalogue
ones.
