Dead link detection:
- Mega-Web: parse hoster error messages (hosterNotAvailable, etc.) from HTML
and throw specific error instead of returning null
- MegaDebridClient: stop retrying on permanent hoster errors
- download-manager: isPermanentLinkError() immediately fails items with dead
links instead of retrying forever
Extraction race condition:
- package_done cleanup policy checked if all items were "completed" (downloaded)
but not if they were "extracted" — removing the package before the last
episode could be extracted
- Both applyCompletedCleanupPolicy and applyPackageDoneCleanup now guard
against premature removal when autoExtract is enabled

- Provider circuit breaker: track consecutive failures per provider with
escalating cooldowns (30s/60s/120s/300s), auto-invalidate Mega-Debrid
session on cooldown
- Escalating backoff: retry delays now scale up to 120s (was 30s max),
unrestrict backoff exponential instead of linear 15s cap
- Shelve logic: after 15 consecutive failures, item pauses 5 min with
counter halving for gradual recovery
- Periodic soft-reset: every 10 min, reset stale retry counters (>10 min
queued) and old provider failures (>15 min), acts like mini-restart
- Mega-Debrid queue timeout: 90s wait limit in runExclusive to prevent
cascade blocking behind stuck calls
- Provider-cooldown-aware retry delays: items wait for provider cooldown
instead of retrying against broken service
- Fix: reconnect/package_toggle now persist retry counters (previously
lost on interruption, defeating shelve logic)
- Mega-Debrid generate: tighter timeouts, progressive reload backoff,
hoster retry limit (5x max)

- Add 30s fetch timeouts to ALL API calls (Real-Debrid, BestDebrid, AllDebrid, Mega-Web)
- Fix race condition in concurrent worker indexing (runWithConcurrency)
- Guard JSON.parse in RealDebrid response with try-catch
- Add try-catch to fs.mkdirSync in download pipeline (handles permission denied)
- Convert MD5/SHA1 hashing to streaming (prevents OOM on large files)
- Add error handling for hash manifest file reading
- Prevent infinite hangs on unresponsive API endpoints
