fix: harden empty-parent pruning boundary and cleanup

Use a path-boundary check instead of a string prefix so sibling dirs
(e.g. _bmad2) can't match the bmad root, and make the walk best-effort
so a dir that vanishes or fills in mid-walk never aborts the install.
Move the test fixture cleanup into finally so failures don't leak temp
dirs.
