execution.SSHHost.execute is now the only way the agent runs anything (L13). Commands travel as a script on SSH's stdin, so the secrets handed to a call are never on a command line, and every value handed out is redacted from the output. Timeouts kill the remote process group, and an unreachable host is reported as such, not as a failed command. Workspace and GitRepo run on the build VM. The clone uses the repository's SSH URL, so no credential is stored in it (#89); fetches and pushes get the push key over stdin, in a short-lived ssh-agent, and PRs are still opened from the agent's host with its API token. The bench runs on the build host too. Tests reach "the build VM" through a throwaway local sshd (nisse_dev .testing); CI installs openssh-server. The live push test now pushes with the sandbox's deploy key (NISSE_PUSH_KEY). Fixes #89.
