Fix:#2328

[Ankit-cs]

Changes

Updates hack/install-spruce.sh to securely download the matching SHA1 checksum asset and verify the Spruce binary's integrity (sha1sum --check) before installing it.

This resolves a potential vulnerability where corrupted or maliciously modified binaries could be silently executed and installed, bringing the script in line with the secure validation pattern already used in install-kubectl.sh.
