HarborDrop 1.4

This release makes browser handoff outcomes verifiable, keeps failed requests visible, and gives users clearer recovery and Settings workflows.

New

Added typed recovery actions for failed downloads, including retry with one connection, redownload from the source page, choose another folder, and open Video Tools when appropriate.
Added session attention badges for newly completed and failed downloads, plus menu bar handoff status and counts.
Added explicit waiting-state descriptions for queued, host-spacing, manually paused, and restored downloads.
Reorganized Settings into General, Downloads, Browser Integration, Categories, Network, Security, Video Tools, and About sections.

Improved browser handoff reliability by waiting for an app admission receipt instead of treating Inbox delivery alone as success.
Improved Failed history so source-context, destination, and other admission failures are recorded instead of disappearing.
Improved Settings persistence with transactional JSON and Keychain handling, rollback recovery, external-change merging, and protected close/quit behavior.
Improved download failure classification across segmented, HLS, extractor, filesystem, and finalization paths.
Improved license verification diagnostics by separating certificate trust failures from transient server outages.

Fixed browser downloads that could be reported as handed off even when the app had not created, queued, or recorded the request.
Fixed retries that could duplicate failed rows or retain stale failure and attention state.
Fixed Settings changes that could conflict with external updates or close while persistence recovery was still required.
Fixed browser-completed import cleanup so the browser record is removed only after HarborDrop has accepted the file.

Updated Full, CWS, and Firefox builds for admission receipts, browser fallback safety, completed-import cleanup, and the latest media classification rules.
