Document the 2.x install matrix and add a migration guide

Install instructions now list the split base MCP SDK packages at ^2.0.0
by role (core comes in transitively, server only for server authors),

mapping. docs/migrate-to-2.md lists the breaking changes, the peer
matrix and the host-side error deltas.
