feat: MCP server v1.2.0 — guide system + read/write guide tools

Adds full guide system to MCP standalone server. System guides (schema,
creating-nodes, edges, dimensions, extract) are bundled and immutable.
Users can create up to 10 custom guides via rah_write_guide. Syncs guide
infrastructure from main repo to OS repo app code.
