Fix brace parsing bug in CLASH_DOWNLOAD_URL_TEMPLATE default value

Browse Source 
The `}` in `{arch}` prematurely closes the `${...:-...}` parameter
expansion, causing the default URL to be truncated to
`clash-{arch.gz}` instead of `clash-{arch}.gz`. The subsequent
`{arch}` replacement then fails silently.

Extract the default URL into a separate variable to avoid the
nested brace conflict.
