Martin Vogel a654acbc88 fix(test-infra): grant the build-dir ACL by SID, not by name (#1532 follow-up)
The local Windows leg caught this within hours of merging #1532: on a machine
that is not domain-joined, USERDOMAIN is the literal string WORKGROUP, and
`WORKGROUP\test` is not a resolvable principal —

    WARN: build-dir DACL stamp (pre-wave) failed (user=WORKGROUP\test ...):
    WORKGROUP\test: No mapping between account names and security IDs was done.

so the grant fails outright and the tree keeps its inherited
`Authenticated Users:(M)`. The guard then correctly reports that cross-account
mutation is still possible, and the whole leg stops. Since most Windows
machines are not domain-joined, that is the common case, not the exotic one.

#1532 was fixing a real bug in the other direction (a bare name resolves
against the machine first, so a host named like its user grants to an empty
principal). Both failures are name RESOLUTION failures, so this stops resolving
names: the account is identified by SID, which is unambiguous everywhere. The
SYSTEM and Administrators grants in these same commands have always used that
form — the current user was the odd one out. Name lookup survives only as a
fallback where PowerShell is unavailable.

Applied to all three scripts carrying the stamp (run-tests-parallel, soak-test,
memlab), since they share the failure and would otherwise drift apart.

PETRO YAKOVYSHYN 3d613a4c9f fix(test): qualify build-dir owner with its domain
The Windows DACL stamps in run-tests-parallel.sh, soak-test.sh and
memlab.sh pass the current user to icacls by bare name. Git Bash resolves
whoami to coreutils, which prints an unqualified name, and icacls resolves
an unqualified name against the machine before the user. On a host whose
name equals the user's (COMPUTERNAME=BUILD with user build) the grant
lands on an empty principal:

    BUILD\:(OI)(CI)(F)

Combined with the /inheritance:r on the same invocation, the directory
ends up granting no usable account. run-tests-parallel.sh then cannot
write its own log directory and the wave dies with:

    build/c/test-logs/results.txt: Permission denied
    FAIL: test-runner --list-suites exited nonzero

Prefix the name with USERDOMAIN when it is set, which makes the account
unambiguous, and fall back to the bare name otherwise. SYSTEM and
Administrators in the same invocations already use SID form and are
unaffected.

Martin Vogel 6a483344c6 feat(diagnostics): deterministic memory-attribution driver
Fixed corpus, fixed request count, one process, no daemon handshake and no
reindex or crash-recovery phases, so two runs differ only where the code does.

Requests go through a request/response driver rather than a batched pipe:
closing stdin makes the server treat it as a client disconnect and shut down
before answering, which yields a census of a process that never worked.

Linux gains a measurement-only --wrap shim so the profiler can observe
allocations the way the Windows interposer already does; macOS has no --wrap
and stays census-only, which the driver reports rather than passing off as
zero.
