Add Cloud Agent development environment config

[asymetryk]

Summary

Sets up and verifies the Cloud Agent development environment for AI Stack Observatory, and captures it as a repository-managed .cursor/environment.json so future agents boot ready-to-work.

What was done

• Verified the toolchain: Node v22.14.0 + pnpm 10.15.0 (via corepack).
• pnpm install --frozen-lockfile — lockfile up to date, 436 packages.
• pnpm lint and pnpm typecheck — clean across all 4 workspace projects.
• pnpm test — 21 tests pass (core: 17, web: 4) plus CLI smoke test.
• pnpm dev — Next.js 15 dev server serves on port 3000.
• CLI (pnpm observatory inspect …) returns the expected WATCH recommendation.
• Browser walkthrough of the analyze flow: https://github.com/example/viking → WATCH, 74% overlap with Graft, 87% confidence (matches the README north-star).

Environment build validation

Validated the config with a clean draft environment build (fresh git clone → corepack prepare pnpm@10.15.0 → pnpm install --frozen-lockfile): SUCCEEDED, install exit code 0, 437 packages, snapshot ready.

Files

• .cursor/environment.json — install runs pnpm install (frozen lockfile), and a web-dev terminal runs pnpm dev.
• .gitignore — allow tracking .cursor/environment.json while still ignoring other .cursor contents.

Notes

No Postgres/Docker was needed for the demo path (the app ships demo/fixture data). The optional contributor Postgres via docker compose is unchanged.
