stale-write-guard-fs MCP

A stdio MCP server that implements a MESI-style cache coherence protocol for shared artifacts in multi-agent LLM systems. It prevents silent data loss from stale-read/write lost updates by enforcing single-writer ordering on a single host. The server exposes ten tools including swg_read, swg_write, swg_reacquire, swg_write_cas, swg_gate, swg_status, and handoff tools to ensure agents do not silently overwrite each other's work on shared files or stores.
