Implements a full downloads manager with Electron main process handling, IPC APIs, and renderer integration. Adds a dedicated downloads page, a mini downloads popup in the navigation bar with progress ring, and controls for pausing, resuming, canceling, opening, and showing downloads. Updates styles and navigation to support the new downloads features.
