Mirror ref/hare/path's impl layout in the test siblings:
abs/isroot/string/local rows -> buffer_test.ww (ref/hare/path/
buffer.ha:28-77); push/parent/pop-split rows -> stack_test.ww
(ref/hare/path/stack.ha:9-180); dirname/basename rows ->
posix_test.ww (ref/hare/path/posix.ha:17-71).
Pure move: every @test block is byte-identical; only the section
banner lines are deleted (file names now carry them) and each
section's ref-cite WHY comment rides with its @test. The suite
header's Hare-vector/parallel-array WHY paragraphs ride with
stack_test.ww (push is their subject); the stale `ww run
lib/path/path_test.ww` sentence is dropped, not relocated.
Consumers: Makefile LIBRARY_TESTS entry replaced in place. The
byteid roster is untouched: lib/path is enrolled there as an
import-probe, not a fixture.
