readPersistedPoolLimits() runs at module evaluation and logs through
rememberLog() on every branch, but hermesLog / desktopLogBuffer /
desktopLogFlushTimer / desktopLogFlushPromise were declared ~110 lines
later. esbuild lowers const/let to var, so the packaged desktop died on
every launch with "Cannot read properties of undefined (reading 'push')"
(#101941, #101960). Moving the four declarations above the read fixes the
crash and keeps the early [pool-limits] line in desktop.log.
Salvaged from #101945 (test dropped: Desktop E2E lane is disabled in CI).
