This adds a new script we can manually run that downloads all the files that need to be uploaded to the mirror and updates our build.zig.zon. The upload still happens manually [by me] but this simplifies the task greatly.

# This script downloads external dependencies from build.zig.zon.json that
|
|
# are not already mirrored at deps.files.ghostty.org, saves them to a local
|
|
# directory, and updates build.zig.zon to point to the new mirror URLs.
|
|
#
|
|
# The downloaded files are unmodified so their checksums and content hashes
|
|
# will match the originals.
|
|
#
|
|
# After running this script, the files in the output directory can be uploaded
|
|
# to blob storage, and build.zig.zon will already be updated with the new URLs.
