Hyperpod Ssm

It wraps AWS Systems Manager to execute commands, transfer files, and run diagnostics on instances. The implementation handles the awkward SSM target format and includes unbuffer to work around an intermittent empty output bug in the session manager plugin. Watch the 3 TPS rate limit when running commands across many nodes. The three shell scripts cover the common pattern: resolve cluster info once, then execute per node. Runs as root by default, uses JSON files for parameters to avoid quoting nightmares.
