This reduces confusion amount users when they download the
intel version and it works super slow. Downloading the arm64
version on an intel mac would just not work.
Users who use intel macs have a habit now (atleast me) to look
for `Intel` version of software when downloading an app. So, made
`Intel` bold to help that process.
This adds the X-Smokescreen-Role header to proxy connections, to track
usage from various codepaths, and enforces a timeout. Timeouts were
kept consistent with their previous values, or set to 5s if they had
none previously.
Leave the Intel build as the prominent default, since it will run on
both platforms. (I would have liked to detect the appropriate
platform, but Apple seems to have put significant effort into making
that impossible for anti-fingerprinting reasons, which is probably an
overall good.)
