v0.13.0

• A download manager: Ctrl+D fetches a URL into a per-session downloads folder (Alt+J opens it) as a background job with a progress bar, resumable and cancellable like a copy; a file already there asks Resume, Overwrite, Rename or Skip through the copy's own dialog.
• The viewer walks links: Tab and Shift+Tab move between them in the rendered view and over bare http(s):// in plain text; Enter downloads a file link or opens a page in the browser, Shift+Enter always opens the browser.
• The viewer has a key bar of its own along the bottom, naming the mode keys and its function keys as the keymap binds them.
• A copy installed with npx holos-installer is offered a self-update when a newer release is out; Skip waits for the next one.
• Keys moved: the change-drive fallbacks are Alt+W and Alt+E, the job queue's Alt+B; the hotlist lives in the drives popup under a divider, freeing Ctrl+D for downloads and Alt+J for the downloads folder.
• The update check runs once at startup (ui.check_for_updates) and blinks a notice on the right status bar until Alt+U dismisses it.
• The About page names the author and the repository, and thanks Christian Ghisler for Total Commander.
