v1.16.0

CLI

• Improved Improved substreams build, substreams protogen and substreams pack command outputs to be streamlined and condensed.

• Added support for reading manifest from stdin across all manifest-accepting commands using "-" as the manifest path. Affected commands: build, run, gui, info, graph, pack, protogen. This enables dynamic manifest generation and preprocessing workflows, including integration with tools like envsubst for environment variable substitution and CI/CD pipeline automation.
