feat: deno-first storage package with sqlite host and graph schemas

Scaffolded @alkdev/storage from @ade/storage_sqlite and @ade/core/graphs:
- graphs/ module: TypeBox schema types + SchemaBuilder (from @ade/core/graphs)
- sqlite/ module: Drizzle table defs, relations, injectable client (from @ade/storage_sqlite)
- pg/ module: placeholder for Postgres host
- deno.json configured for JSR with subpath exports (./graphs, ./sqlite, ./pg)
- Imports swapped: @sinclair/typebox → @alkdev/typebox, drizzle-typebox → @alkdev/drizzlebox
- Client is now injectable (no hardcoded env vars or module-level side effects)
- no-slow-types lint excluded (Drizzle generics); --allow-slow-types on publish
