Subject: [PATCH] fix: carry Linux support through Homebrew cask generation

The tap's Casks/parallel-cli.rb is regenerated from homebrew/parallel-cli.rb
on every release, so parallel-web/homebrew-tap#1 (Linux support) would be
reverted by the next release bump. Mirror that cask in the template
(on_macos/on_linux blocks, macOS-only xattr preflight), add the linux
platforms to the generator's PLATFORMS map, and download their checksums
in the publish-homebrew job.

Verified: the updated generator reproduces the currently-merged tap cask
byte-for-byte for v0.9.3.
