fix(shell): extend project_open scan to find nested-git projects

WordPress projects whose .git lives inside bedrock/ and trellis/
subdirectories (rather than at the project root) were invisible to
the depth-3 scan. Add a depth-4 pass that maps sub-repo paths back
to their parent project directory, deduplicated with sort -u.

Move bats submodule into bin/ and add test fixtures and cases
covering this nested-git structure.
