Synthesis Mac Sync

A methodology for keeping multiple Macs in sync using iCloud for configuration files and Git for repositories, run end to end by the agent: the user says "run my mac-sync" and the agent does it with as few approval prompts as possible. This skill is the protocol; the user's config file in the iCloud sync folder is the specifics (which files, which machines, which repos). Moving work from one Mac to another uses synthesis handoff and the steps in leaving-and-arriving.md, shared with synthesis-machine-sync.
