fix(manager): populate files for completed queued downloads and add retry logic (mainly intended to fix an issue with AllDebrid)

[jedijens]

📌 Description

When uncached torrents finish downloading via a debrid provider (e.g. AllDebrid), processQueuedTorrent detected status TorrentStatusDownloaded but did not call applyDebridTorrentToEntry(entry, debridTorrent).

Because of this omission:

entry.Files remained empty in memory.
processSymlink() received 0 active files, logging Creating symlinks for 0 files... and creating no symlinks (causing Arr import failures).
This PR fixes the issue by:

Calling applyDebridTorrentToEntry(entry, debridTorrent) in processQueuedTorrent() so files returned by debrid status checks are synced to the entry.
Adding a retry safety net in processSymlink() (up to 6 attempts, 10s backoff) that attempts provider/directory re-checks before failing.

Target Branch Check (IMPORTANT)

• I confirm this PR is targeting the correct branch

Expected target:

• beta (for features)

Changes Made

• pkg/manager/processor.go: Called applyDebridTorrentToEntry(entry, debridTorrent) in processQueuedTorrent(). When a queued download completes, files and provider metadata are now correctly synced to entry.Files.
• pkg/manager/downloader.go: Added a retry loop in processSymlink() (up to 6 attempts with 10s backoff) that attempts provider refresh and mount scanning (populateFilesFromMount) before failing with 0 files.
• Dockerfile: Added sed to strip potential CRLF carriage returns from /entrypoint.sh during image build.

---

Testing

• Tested locally

Steps:

1. Built container image using Docker Compose on Linux host.
2. Submitted an uncached season pack via Sonarr with AllDebrid provider.
3. Monitored logs while the torrent finished downloading in the queue: verified applyDebridTorrentToEntry properly populated all files and symlinks were created successfully (Creating symlinks for 10 files...), allowing Sonarr to import the release immediately.

Risks / Notes

• None identified. Should be safe and backward-compatible fix.
