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.

Extracts yt-dlp argv construction out of download.ts into its own
electron-free module (src/main/buildArgs.ts) so it can be exercised by
vitest without spinning up Electron, plus a real-download integration
test (skipped by default; opt in with AEROFETCH_REAL_DOWNLOAD=1) that
spawns the bundled yt-dlp.exe/ffmpeg.exe against its argv. download.ts
isn't wired up to it yet — that lands with the next commit.
This was done in an earlier local session but never actually committed,
even though download.ts has imported from it since the Phase A commit
(bb5dd6c) — the build had been relying on an uncommitted local file.
