Hojun-Cho a95a7a316b test/wcc: carrier ownership repair and driver-contract adaptation
Every surviving carrier now owns its artifacts: checked mkdir/mkdtemp/
fopen acquisition, one all-exit cleanup funnel per carrier, ENOENT-
tolerant checked unlinks, exact-path deletion (rm -rf only for an
owned pid-keyed dir or a .sepwork beneath one), and cleanup failure
fails a passing carrier without overwriting its diagnostic. In the
same pass the carriers adapt to the driver contract this branch lands:
--sep and WW_PKGCACHE are gone, -S and the /tmp/ww_run_<pid> scratch
contract are asserted, and rows whose runtime or reject coverage moved
to test/wcc/data fixtures or test/lang @test owners are trimmed to the
byte/artifact/diagnostic observations only they can make.

Repair and adaptation ride together because most files interleave both
in the same hunks; splitting would manufacture intermediate carrier
states that never existed and cannot run against either driver.

/*
* 976_stat_run — execute the lib/os stat fixture under the C-side
* `ww test` driver and assert exit 0.
*
* Workflow (mirrors 975_dirs_run's mkdtemp + exact-cleanup shape):
* 1. mkdtemp /tmp/wwstat-XXXXXX — fresh per run, no parallel-test
* contention.
* 2. Populate the scratch tree:
* <tmp>/regfile regular file, 11 bytes "hello world"
* <tmp>/symlink → ./regfile (relative symlink)
* <tmp>/subdir directory, mode 0700
* 3. setenv WW_TEST_STAT_REGFILE / SYMLINK / SUBDIR / NOENT with
* the absolute paths; lib/os/stattest.ww reads them via
* os.getenv and exercises stat/lstat/fstat/exists.
* 4. exec `ww test lib/os/stattest.ww`.
* 5. Remove the exact children and then the mkdtemp-owned root.
*
* Same wrapper shape as 970-975; cleanup runs on success and failure.
