Meta Vens 5646ff7351 Land the QUIC Cut 3 eighth fix batch: release config, whole-duration seam, pollhammer live objects, zero-timeout bound, closerace starvation fix
Self's ruling of 2026-09-22 named six findings against Soul's eighth pass.
This lands the code side of all six:

- The wait-record seam (CULTMESH_QUIC_DEBUG_RECORD_WAIT) now wraps the whole
  duration handed to `wait_for`, not the raw `timeout_ms` before it is
  converted to milliseconds, so arithmetic applied after that conversion can
  no longer live outside what the seam records. Its "unset" sentinel moves to
  a separate `debug_wait_recorded` flag so a recorded -1 could never be
  confused with nothing recorded.
- `pollhammer` also runs against a runtime holding a live connection to an
  unroutable address (RFC 5737 TEST-NET-1), a best-effort stream on it, and a
  real (never-connected) listener, closing the gap where the wait's predicate
  was only ever exercised on an empty runtime.
- A new `zerotimeout` scenario pins that `timeout_ms <= 0` returns within
  50 ms, probing 0, -1 and INT32_MIN.
- `closerace`'s settle no longer sleeps a guessed duration: where the
  development seam exists it waits for `debug_peak_calls` to reach the poller
  count (reset before any poller thread exists, so nothing can zero a count a
  poller already raised) before a short fixed margin closes the last gap
  between being counted and being inside the condition wait.
- `kGenerousLateToleranceMs` narrows from 800 ms to 400 ms so the wall-clock
  scenarios can catch arithmetic applied outside the seam's own argument,
  which `waitseam`'s equality check structurally cannot see.

scripts/mutate-cultmesh.mjs gains a plain `release` configuration on both
platforms (CULTMESH_QUIC_DEBUG_ASSERTS=OFF, CMAKE_BUILD_TYPE=Release) running
`polltimeout`, `pollbusy`, `pollhammer` and `zerotimeout`, and seven new
mutation entries: R1 (the release macro divides the duration by 10), W1-W3
(600 ms added, a 500 ms floor, and a 1000/909 scale, each applied outside the
seam's own argument), P1 (the idle predicate also ends on a live connection),
and Z1-Z2 (a 500 ms sleep and a 300 ms spin on a non-positive timeout). Two
stale comments are corrected: the scenario list above `assertScenarios` now
names `pollhammer` among the clock-sensitive entries, and a historical "1300"
probe value that no longer matches the test file is removed. The header's
section 7 intro now says the seam serves both the quiesce and the wait
recording, not quiesce alone.
