v0.5.0

Added

• Batch operations: pause_all(), resume_all(), and cancel_all() engine APIs with per-download outcomes reported via the new BatchResult type (#11)
• Pluggable persistence: DownloadEngine::with_storage() accepts any custom Storage implementation, enabling resume-from-breakpoint without the built-in SQLite storage or the storage feature (#11)
• FileStorage: built-in file-based storage using one JSON sidecar per download (aria2 control-file analog) with atomic temp-file writes
• Segment and SegmentState now derive Serialize/Deserialize, and async_trait is re-exported from gosh_dl::storage, making third-party Storage implementations easier

Changed

• pause() (and pause_all()) now accepts downloads in the Queued state, so pausing the whole queue no longer lets waiting downloads get promoted into freed slots
• Recursive discovery now fetches pages concurrently, honoring the previously unused RecursiveOptions::max_discovery_concurrency option (#10)
• Updated transitive dependencies to pick up security fixes: quinn-proto 0.11.14, aws-lc-rs 1.17.0 / aws-lc-sys 0.41.0, rustls 0.23.40, rustls-webpki 0.103.13, reqwest 0.13.4, rand 0.9.4 / 0.10.1

Fixed

• Pausing or cancelling a queued download no longer leaves an orphaned entry in the priority queue that could later acquire a download slot
• CI workflow now declares least-privilege permissions: contents: read
