- sign-windows.sh: jsign wrapper using Trusted Signing service principal
via OAuth client_credentials flow. Reads SP creds from
/etc/gururmm-signing.env (root-only). Uses RFC3161 timestamping (jsign's
default Authenticode mode fails against Microsoft ACS).
- build-agents.sh: now signs the Windows binary in-place after cargo build
and computes sha256 AFTER signing so consumers get correct hashes.
- Updated -latest symlinks for both Linux + Windows in the build script.
