Subject: [PATCH] Make install script backward compatible with old and new
 release formats

The install script now tries checksums.txt first (v4.29.0+), then falls back
to individual .sha256 files (v4.28.0 and earlier). This ensures users can
update from any version regardless of which checksum format was used.

This fixes the release format transition issue where changing asset structure
broke updates for users on older versions.
