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

WordPress projects like clinimed hold .git inside bedrock/ and trellis/
subdirectories rather than at the project root, so the depth-3 scan
missed them. Add a depth-4 pass that maps sub-repo paths back to their
parent project directory, with sort -u to deduplicate.

Move bats submodule to repo root and add test fixtures covering this
nested-git structure.
