`import a.b as X` written inside a function binds X there, ahead of any
module-level binding of X, so X.f() reaches a/b.py's f, as the same
import at module level already did. An undotted alias is left alone,
since an optional dependency's name can match any project file.
mealie's lifespan_fn now links init_db.main; the other repos are
unchanged.
Fixes issue 2600.
