9-phase plan for the cmem-sdk package (embeddable claude-mem I/O on
Postgres runtime) and the foundational `server-beta` → `server` rename.
Phase 1 (rename) is independently shippable and fixes the silent
runtime regression in `runtime-selector.ts` where only the literal
`server-beta` was accepted as the runtime value. Phases 2-9 ship the
SDK on top.
