v0.7.2

Fixed

• Prevented yt-dlp and JavaScript child processes from keeping metadata fetches or canceled downloads alive indefinitely.
• Replaced the repeatedly extracted one-file yt-dlp build with a stable prewarmed runtime cache.
• Bundled Deno so YouTube JavaScript challenges and formats above 720p do not depend on system-installed tools.
• Stopped masking empty-format extraction failures and removed brittle forced YouTube client selection.

Changed

• Pinned and checksum-verified yt-dlp, Deno, FFmpeg, aria2, and aria2's libraries for matching local and GitHub Actions builds.
• Removed aria2's runtime dependency on Homebrew and configured its bundled CA certificate for direct and yt-dlp-delegated HTTPS downloads.
• Added bounded network retries and optional aria2c acceleration for large direct media downloads.
