- Always force re-download once when both JVM and legacy extractors fail
(suggestRedownload=true), regardless of valid archive signature
- Add autoRecoveredForRedownload Set for loop protection (one attempt per archive)
- Clear loop protection on package reset (clearHybridArchiveState)
- Previous sibling-items check failed when other episodes were already
cleaned up after hybrid extraction
- Lower mini-download retry threshold from 100KB to 5KB

- Retry extraction with 2.5s delay on CRC/password errors (Windows file handle race)
- Improve auto-recovery: force re-download when known password fails (content corruption)
- Expand auto-recovery to wrong_password category for encrypted RAR5
- Add fsync after download for pre-allocated files
- Fix permanent extraction failure loop for archives with valid headers but corrupt content

- Switch JVM GC from SerialGC to G1GC with MaxGCPauseMillis=50
for shorter pause times in long-lived daemon
- Increase JVM heap from 512m/8g to 1g/32g to reduce GC pressure
on systems with plenty of RAM
- Raise hybrid thread cap from floor(cpuCount/2) capped 8
to ceil(cpuCount*0.75) capped 12 — downloads are I/O-bound
and don't need much CPU headroom
- Refresh daemon process priority before each request so hybrid
extraction gets correct CPU priority even if daemon was started
with a different priority level

- Early-exit now also uses raw Content-Length as fallback when
totalBytes is unknown (provider returned fileSize=0)
- Stall handler checks if file is already complete on disk before
deleting and retrying — prevents re-download loop for files that
finished but server delayed closing the connection

- Add scheduler generation counter to prevent stale scheduler from
continuing after stop/start cycle
- Guard processItem stop-abort handler: skip status overwrite when a
new start() has already re-activated the session
- Yield in start() after recoverRetryableItems to let pending abort
handlers complete before evaluating item states
- Add test: rapid stop → disable provider → start must resolve

Files with valid RAR/7z/ZIP signature are not corrupt (wrong password),
only files with invalid signature get force-redownloaded.

- Trust extractor CRC verdict over file size checks
- Re-queue incomplete downloads instead of just warning

If the primary extractor (7-Zip) fails with wrong_password/checksum
error on a .rar file, automatically try the alternative extractor
(UnRAR/WinRAR) which handles RAR format natively and more reliably.

Items incorrectly marked as "completed" by the old 50% recovery threshold
persist in the session file across updates. On startup, check all completed
items: if the file on disk is smaller than expected totalBytes, reset to
"queued" so it gets re-downloaded. Also reset items whose files are missing.
