The flag was added in Node 24. On older runtimes node exits immediately
with "bad option" before the daemon can write any log, create the
session directory, or bind its socket. The client process has no
visibility into the spawned daemon (stdio is ignored and no exit
listener is attached), so the user only sees "Failed to start daemon:
session not validated after 500ms" with no indication that the daemon
crashed on startup.
Pass the flag conditionally based on process.versions.node, and warn
on stderr when a proxy env var is set but the runtime is too old to
honor it.

startNewDaemon previously spawned the daemon with stdio: 'ignore' and
no exit listener, so any spawn-time failure (unsupported Node flag,
missing dependency, immediate crash) surfaced only as a generic
"session not validated after 500ms" timeout. The user had no way to
tell whether the daemon was slow to start or had died on launch.
Attach 'exit' and 'error' listeners to the spawned child and check
them on every phase 1 polling iteration (and once after the loop, in
case the daemon exits while a final validation is in flight). When
the daemon dies early, throw an error that includes the exit code or
signal and points the user at the session log directory.
