This catalogues the remaining GNU coreutils 9.11 test-suite failures so they
can be tracked and worked on individually. Totals from the aggregated run:
~690 tests — 625 PASS / 55 FAIL / 9 SKIP / 1 ERROR.

Tests that cannot pass for structural reasons (they intercept glibc calls via
LD_PRELOAD, or drive uutils through gdb breakpoints) are separated into the
INCOMPATIBLE section, since they depend on internal implementation details we
do not match. A few entries are marked (intermittent) — they are listed in
.github/workflows/ignore-intermittent.txt and fail only sporadically.
