Re-aligns scripts/Agents CLI.app.sha256 with the rebuilt + notarized helper
that has the keychain-access-groups entitlement and embedded provisioning
profile (from PR #210). Commit e772a19a reverted this to the broken 1.20.4
SHA; this brings it back so 1.20.5 ships the fixed helper that works on
macOS 26.

New SHA: 4d46fe0cc7afd6deb3ba0ad2ffcb12e2f4074a79e7618b4f0eafff55d458d507
