Depending on yt-dlp[deno] puts a deno binary in the environment's bin
directory, and the code assumed yt-dlp would then find it. That only holds
while that directory is on PATH, which is true under `uv run` in the checkout
and false once the package is installed as a tool: only the console script is
exposed. Installed that way, doctor reported "only nvm node ... invisible to
cron" while a 95 MB deno sat unused in the tool's own bin, and YouTube
extraction was one nvm-less environment away from failing outright -- the exact
failure the deno dependency was added to prevent.
Runtimes are now resolved against sys.prefix before PATH and passed to yt-dlp
as an absolute path, which its js_runtimes config documents. That also removes
the special case that made node the only runtime resolved to a real path.
The doctor tests hid this: they faked absence by patching shutil.which alone,
so the real deno was found regardless and one of them passed for the wrong
reason. They now hide it from both lookups.
