Implements the remaining Phase B (Access & networking) items from ROADMAP.md: cookie sources (browser cookie-store import, or a built-in sign-in window that exports a Netscape cookie file via a persisted Electron session partition), the aria2c external downloader, proxy/rate-limit, restrict-filenames, and a download-archive to skip repeats. Wires download.ts to the buildArgs() module added in the previous commit (it wasn't hooked up yet) and renames its options param NetworkOptions -> AccessOptions to reflect the wider scope now that cookies and filename/archive flags joined proxy/rate-limit/aria2c.
