fix: move @framers/sql-storage-adapter from peer to dependencies

It was a peer marked optional, but core/storage/SqlStorageAdapter.ts
imports it eagerly at module load. Consumers got 'Cannot find package
@framers/sql-storage-adapter' on bare `import { agent } from '@framers/agentos'`
unless they manually installed it.

Either the runtime should lazy-load it (so the peer-optional contract
holds) or it belongs in dependencies. Making it a hard dep is the simpler
fix — sql storage is on the default code path through ConversationManager
and most consumers want it.
