docs: add AGENTS.md and fix agent role defs for deno-first project

- Add AGENTS.md with project overview, conventions, commands, and heritage notes
- Fix all npm→deno command references in coordinator, implementation-specialist, poc-specialist
- Fix project name in coordinator spawn template (@alkdev/operations→@alkdev/storage)
- Remove hub-specific content (future model, hub operations) from coordinator
- Add project-specific conventions to implementation-specialist (no comments, TypeBox, slow types, etc.)
- Add deno-specific review checks to code-reviewer
- Fix file path examples in implementation-specialist (packages/core→src/graphs)
- Update sdd_process.md to remove hub-specific references and architecture doc list
- Update architect examples to use storage component names

+## Project Conventions (@alkdev/storage)
+
+Read `AGENTS.md` at project root for full details. Key rules:
+
+1. **No comments in code** — Per project convention.
+2. **TypeBox, not Zod** — Use `@alkdev/typebox` and `@alkdev/drizzlebox` for schema/validation.
+3. **Explicit .ts extensions** — All imports must include the `.ts` extension (Deno convention).
+4. **JSR slow types** — Drizzle's deeply inferred generics make explicit annotations impractical. Use `--allow-slow-types`. Do not annotate drizzle table definitions.
+5. **Injectable clients** — `createSqliteDatabase(client)` takes a client, not env vars. No module-level side effects.
+6. **Naming conventions** — TypeBox schemas: PascalCase (`NodeType`). Drizzle tables: camelCase (`graphTypes`). Drizzlebox schemas: PascalCase (`InsertGraph`).

 ## Key Principles
 
 1. **Read first** - understand before implementing
