- 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

- 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)

WinRAR doesn't support \?\ prefix (interprets it as UNC network path).
Replace with subst drive mapping: maps targetDir to a short drive letter
(Z:, Y:, etc.) before extraction, then removes mapping after. This keeps
total paths under 260 chars even when archives contain deep internal
directory structures.

Add longPathForWindows() helper that prefixes extract target directories
with \?\ on Windows, bypassing the 260-char MAX_PATH limit. Applied to
both WinRAR/UnRAR and 7z arguments. Fixes "Die Syntax für den
Dateinamen, Verzeichnisnamen" errors when archive internal directories
create deeply nested output paths.

- Add multi-threaded extraction via WinRAR -mt flag (uses all CPU cores)
- Fix -idq flag suppressing progress output, replaced with -idc
- Fix extraction timeout for multi-part archives (now calculates total size across all parts)
- Raise extraction timeout cap from 40min to 2h for large archives (40GB+)
- Add natural episode sorting (E1, E2, E10 instead of E1, E10, E2)
- Add split archive support (.zip.001, .7z.001) with proper cleanup
- Add write-stream drain timeout to prevent download freezes on backpressure
- Fix regex global-state bug in progress percentage parsing
- Optimize speed event pruning (every 1.5s instead of every chunk)
- Add performance flag fallback for older WinRAR versions
