User-Report: Logs zeigten z.B. "17:29:43" obwohl es lokal 19:29:43 war (CEST/UTC+2), weil
alle Logger `new Date().toISOString()` (UTC "...Z") nutzten. Neuer Helper logTimestamp()
formatiert lokale Zeit mit explizitem Offset (ISO 8601, z.B. "2026-05-31T19:29:43.605+02:00")
— menschlich lokal UND weiterhin eindeutig/Date.parse-bar. Angewandt auf alle Log-Zeilen-
Writer: item-log, logger (rd_downloader.log), audit-log, rename-log, session-log,
package-log, account-rotation-log, trace-log. Interne/API-/Dateinamen-Zeitstempel
(debug-server, support-bundle, trace autoDisableAt-Config) bleiben absichtlich UTC.
Test: tests/log-timestamp.test.ts (Format + Round-Trip zum selben Instant + lokale Stunde,
TZ-unabhaengig). 650 Tests gruen, tsc 9, Build sauber.

- Convert all sync FS ops (existsSync, readdirSync, statSync, writeFileSync,
rmSync, renameSync) to async equivalents across download-manager, extractor,
cleanup, storage, and logger to prevent UI freezes
- Replace linear retry delays with exponential backoff + jitter to prevent
retry storms with many parallel downloads
- Deduplicate resolveArchiveItems into single shared function
- Replace Array.shift() O(N) in bandwidth chart with slice-based trimming
- Make logger rotation async in the async flush path
