The bundled yt-dlp is a PyInstaller one-file binary that unpacks ~37MB
on every invocation, costing about eight seconds a call on this machine
regardless of signing, xattrs or thinning the universal binary. Homebrew's
copy is a Python script and starts instantly, so bundling traded startup
speed for self-containment.
Softens it where possible: tool versions are read once at startup in the
background rather than on every Settings open, and resolved stream URLs
are cached for three hours (well inside YouTube's signed-URL lifetime) so
replaying a video costs nothing. A first play still pays the startup.
