init

Initialise the current Git repository as a SAF workspace of the poesis-saf-agentic-organization framework: checks Git and the Git identity, writes the committed workspace marker .saf/workspace.yaml and the repository plugin settings .github/copilot/settings.json, then commits both. Use when an orchestrator reports that this folder is not a SAF workspace, or when the user asks to initialise, set up or bootstrap a SAF workspace.
