Fix create-basis package resolution to use resolved basis libs

Rewrites `create-basis` to replace `:local/root` workspace dependencies
by iterating over the resolved basis `:libs` map instead of the package's
`:depends-on` set. This ensures correct resolution even after `filter-by`
clears `:depends-on`, and preserves non-workspace libs unchanged.

Adds tests covering local dep replacement, filtered packages, non-workspace
libs, and libs with no version.
