Copper Download Manager v0.5.6

v0.5.6 — Universal file-format filter (Formats tab)

File Format Filter now actually works for all downloads

• Moved to its own dedicated "Formats" tab in Settings, placed right between the Downloads and Tools tabs.
• Now enforced for every download path (manual Add URL, copper://, the API, the browser extension, and playlist/yt-dlp children) — previously the filter wasn't applied consistently.
• Semantics: the Exclude list always blocks those formats; the Include (Allow) list lets only the formats listed; a URL with no extension is always allowed. Defaults: all image formats excluded, all non-image formats allowed.

Removed the old per-type filter

• The "Download Type Filter" (Allow/Block per category) option was removed. The app now uses a single, simpler, universal file-format filter instead of confusing per-category rules.

Extension update

• Chrome + Firefox extensions bumped to 5.4.0.
• Browser download auto-capture uses the same include/exclude lists from /api/download-filters, so the extension blocks the same formats as the app.

Build

• 44/44 integration tests passing; extension validator green.
• Artifacts: CopperDownloadManager-0.5.6-setup.exe and CopperDownloadManager-0.5.6-portable.zip.
