When SevenZipJBinding reports "Archive file can't be opened with any
of the registered codecs", the extractor now falls back to legacy
UnRAR instead of failing immediately. Previously, backend mode "jvm"
(the production default) only allowed fallback for UNSUPPORTEDMETHOD.

- Encrypt sensitive credentials (tokens, passwords) in backup exports
using AES-256-GCM with PBKDF2 key derivation from OS username
- Backup format v2 with backwards-compatible v1 import
- Show dialog to create non-existent directories when changing
outputDir, extractDir, or mkvLibraryDir settings

Root cause: SevenZip.initSevenZipFromPlatformJAR() was never called, so
native compression codecs (RAR5, LZMA2, etc.) were not loaded. Archives
could be opened (header parsing is pure Java) but all extractSlow() calls
returned UNSUPPORTEDMETHOD because no native decoder was available.
- Add ensureSevenZipInitialized() with lazy init before extraction
- Pass password to extractSlow(outStream, password) for RAR5 compatibility
- Add UNSUPPORTEDMETHOD -> legacy fallback in extractor.ts as safety net

Java's getCanonicalFile() resolves subst drives inconsistently,
causing secureResolve() to falsely block valid filenames. JVM handles
long paths natively so subst is only needed for legacy UnRAR/7z.

The JVM sidecar class files were packed inside app.asar where Java
cannot access them. asarUnpack extracts them to app.asar.unpacked/.
Default backend changed from auto to jvm (no legacy fallback).

- New JVM sidecar (resources/extractor-jvm/) using SevenZipJBinding for
RAR/7z/TAR and Zip4j for ZIP multipart, matching JDownloader 2 stack
- Auto/JVM/Legacy backend modes via RD_EXTRACT_BACKEND env variable
- Fallback to legacy UnRAR/7z when JVM runtime unavailable
- Fix isJvmRuntimeMissingError false positives on valid extraction errors
- Cache JVM layout resolution to avoid repeated filesystem checks
- Route nested ZIP extraction through JVM backend consistently

- setWindowsBackgroundIO (Very Low I/O) now only applied in hybrid mode,
not for all extractions (was causing massive slowdown)
- Hybrid threads changed from -mt1 to half CPU count (e.g. -mt4 on 8-core)
- Move retry count (R9, R22 etc.) from status text to tooltip only

- normalizeSessionStatuses: reset all queued items to "Wartet" instead of
only checking a few specific patterns (missed Retry, Unrestrict-Fehler etc.)
- Reset completed items with stale extraction status to "Fertig (size)"
- stop(): reset all non-finished items to queued/"Wartet" and packages to queued

- Add disk space check before extraction (aborts if insufficient space)
- Add single-level nested archive extraction (archives inside archives)
- Blacklist .iso/.img/.bin/.dmg from nested extraction
- Set real Windows I/O priority (Very Low) on UnRAR via NtSetInformationProcess
- Reduce UnRAR threads to -mt1 during hybrid extraction
- Fix double episode renaming (s01e01e02 pattern)

Items with transient status texts like Provider-Cooldown, Warte auf
Daten, Verbindungsfehler are reset to "Wartet" when the app restarts,
so they don't show misleading status from a previous session.

- Debounce: simultaneous failures within 2s count as 1 failure
(prevents 8 parallel unrestrict failures from instant-triggering)
- Raise threshold from 8 to 20 consecutive failures before cooldown
- Escalation tiers: 20→30s, 35→60s, 50→120s, 80+→300s

- Pause now aborts active extractions (previously extraction continued
during pause, showing wrong status like Provider-Cooldown)
- Unpause clears provider circuit breaker for fresh start
- Post-processing status checks account for global pause state
- Reduce stall detection timeout from 30s to 15s for faster retry
- Reduce stall retry base delay from 500ms to 300ms

- Add pause check at top of processItem retry loop so items show
"Pausiert" instead of "Provider-Cooldown" when paused
- Lower extraction process priority from BELOW_NORMAL to IDLE
(IDLE_PRIORITY_CLASS on Windows also lowers I/O priority, reducing
disk contention between extraction and active downloads)
