chore: development environment setup for Cloud Agents

[bmdavis419]

Summary

Sets up the development environment for Cloud Agents working on this codebase.

Changes

• apps/dashboard/package.json: Added drizzle-orm as a direct dependency. The dashboard imports drizzle-orm in src/lib/server/dashboard.ts but it was only a transitive dependency via @ns-sentinel/db. Vite's SSR module resolution requires it to be declared directly for the dev server to work.
• AGENTS.md: Added ## Cursor Cloud specific instructions section with:
  • Repository structure overview
  • Key commands reference
  • Non-obvious caveats (Docker setup, non-TTY drizzle-kit, env file, pre-existing type errors in crawl-helpers)

Update Script

Minimal bun install to keep dependencies fresh on each Cloud Agent session.

Testing

• bun run format:check — passes
• bun run check — dashboard now passes (9/10 packages pass; crawl-helpers has pre-existing type errors on main)
• bun run dev:dash — dashboard dev server starts and serves pages successfully on port 5173

  

Note

Add development environment setup guide and drizzle-orm dependency for Cloud Agents

• Adds a new 'Cursor Cloud specific instructions' section to AGENTS.md covering monorepo structure, key commands, Docker requirements, and .env setup.
• Adds drizzle-orm@^0.45.2 as a direct dependency to apps/dashboard/package.json to satisfy a previously implicit peer dependency.
