Administrator d9c3a00016 test(log): extract log-rotation into testable module + 10 unit tests
The fileuploader.log rotation introduced in 3.3.2 lived inline in
main.js — fine for the runtime path, but it required electron's `app`
to even reach the function under test. Pull the rotation logic into
lib/log-rotation.js (pure fs/path, no electron deps) and cover it
properly:

- ENOENT (file missing) → no-op
- Below cap → no-op
- Over cap → live → .1, returns true
- Existing backups shift up: .1 → .2, .2 → .3
- At maxBackups limit → oldest dropped, others shift, live becomes .1
- Idempotent: rotating twice keeps the chain consistent
- maxBackups=1: never grows past .1
- Invalid maxBytes (0/negative/NaN) → safe no-op
- Provided debug callback receives a "rotated" message
- File without extension still rotates correctly

main.js now imports `maybeRotateLogFile` and calls it directly. 97/97
tests pass.

# Verbesserungs-Loop — open items
## Released
- ✅ 3.3.0 — Performance-Fixes (queue-cap, sort-throttle, history-delegation, recent-cap) + Log-Recovery
- ✅ 3.3.1 — `removeFromQueueOnDone` coalesced via microtask (kein O(N²) mehr bei done-Bursts)
- ✅ 3.3.2 — `fileuploader.log` Auto-Rotation bei 50 MB (max 3 Backups: .1 .2 .3)
- ✅ 3.3.3 — `_jobLogCollector` Cap auf 1000 tracked jobs (FIFO-eviction beim Überschreiten)
- ✅ 3.3.4 — `applyQueueSelectionClasses` + `applyRecentSelectionClasses` nutzen `getElementsByClassName` (live HTMLCollection statt querySelectorAll re-query bei jedem Klick)
- ✅ 3.3.5 — Log-Rotation extrahiert nach `lib/log-rotation.js` + 10 neue Unit-Tests (cap, shift, eviction, idempotency, maxBackups=1, invalid input, no-extension)
## Open items (priorisiert)
### Code-Qualität
- [ ] queue-cap-prune-Logik (3.3.0 handleBatchDone) — DOM-abhängig, bräuchte jsdom; deferred bis sich anderes lohnt
- [ ] sortQueueJobs dynamic-throttle (3.3.0) — modul-state-abhängig im renderer; deferred
### UX-Politur
- [ ] **CSS `.queue-row` transition** auf `:hover` scopen (aktuell auf jedem row → unnötiger Repaint bei Status-Flip).
- [ ] Module-level Sets `_sessionTrackedJobs`/`_sessionDoneJobs`/`_completedUploadKeys` werden nie geleert — minor memory growth.
## Loop-Notes
- Cron-Job `01e33ae1` läuft alle 30min (:07/:37), Session-only.
- Pro Iteration: GENAU EIN Issue. Auto-Release bei grünen Tests. Boundary: keine Features, keine Major-Refactors.
