When Promise.race() or Promise.any() settles, V8 fires
kPromiseResolveAfterResolved / kPromiseRejectAfterResolved for each
"losing" promise. The PromiseRejectCallback in node_task_queue.cc was
crossing into JS for these events, but since the multipleResolves
event reached EOL in v25 (PR #58707), the JS handler does nothing.

The unnecessary C++-to-JS boundary crossings accumulate references in
a tight loop, causing OOM when using Promise.race() with
immediately-resolving promises.

Return early in PromiseRejectCallback() for these two events, skipping
the JS callback entirely. Also remove the dead case branches and
unused constant imports from the JS side.

Move early returns for kPromiseResolveAfterResolved and
kPromiseRejectAfterResolved before Number::New and CHECK(!callback),
avoiding unnecessary work. Remove dead NODE_DEFINE_CONSTANT exports
and fix comment placement in the JS switch statement. Bump test
--max-old-space-size from 20 to 64 for safety on instrumented builds.

Use performFileOperation() for test runner watch updates so the

Repeated writes can trigger another watch restart while the previous
rerun is still active. The runner then terminates the in-flight child
process with SIGTERM, which can make the captured output include both
a failed file-level subtest and the next successful run.

Also count only root summary duration lines when detecting completed

Several prose references to HTTP, HTTPS, SSL, HPE_HEADER_OVERFLOW
and ECMAScript used the article "a" where the acronym starts with
a vowel sound and should take "an". The rule is based on
pronunciation, not spelling: HTTP is read "aitch-tee-tee-pee",
SSL is read "ess-es-el", ECMAScript is read "ek-mah-script",
and HPE is read "aitch-pee-ee" — all starting with a vowel sound.

Affected files:

* doc/api/crypto.md — "disable a SSL 3.0/TLS 1.0 vulnerability"
* doc/api/http.md — five occurrences ("a HTTP '400 Bad Request'",
  "a HTTP '431 Request Header Fields Too Large'", "a HTTP/1.1 102
  Processing message", two copies of "use a HTTP parser") plus
  two references to "a HPE_HEADER_OVERFLOW"
* doc/api/http2.md — two code-sample comments reading
  "// Detects if it is a HTTPS request or HTTP/2"
* doc/api/module.md — "compiles a CommonJS, a ECMAScript Module,
  or a TypeScript module" (only the middle article changes; the
  adjacent "a CommonJS" and "a TypeScript" are both correct)
* doc/api/tls.md — two references to "part of a SSL/TLS handshake"
