Set up Cursor Cloud dev environment (pnpm) and correct AGENTS.md

[ceccec]

What

Sets up and verifies the development environment for this VitePress v2 (alpha) pnpm-workspace site, and corrects AGENTS.md, whose Cursor Cloud instructions said the project uses npm when it actually uses pnpm (pnpm-lock.yaml, pnpm-workspace.yaml, packageManager: pnpm@11.6.0, and CI's pnpm install --frozen-lockfile).

Environment setup

• Update script (startup): corepack enable pnpm + pnpm install --frozen-lockfile.
• Node: CI uses 24; the dev server and the vitepress build step also run on the login-shell default (nvm Node 22.x).

AGENTS.md corrections (only clearly-incorrect / durable items)

• npm → pnpm across the quick-reference table and notes (npm ci would fail — there is no package-lock.json).
• Documented that docs:build is heavy and currently red: vitepress build renders ~400 pages in ~3 min and works, but the enforcement-trinity fold wave (modelSeal over the ~2.3 MB src/quantum/mind/index.ts) is single-threaded, takes ~50 min, and currently fails with open gates (quantify.gates, dimensions.emerge.within) — reproduced identically in CI (.github/workflows/deploy.yml), i.e. a pre-existing model/seal issue, not an environment problem. The dev server is the practical way to develop/preview.
• Noted that check:types (tsc) can't run because TypeScript is not a declared dependency (CI doesn't run it).
• Noted the non-login PATH /exec-daemon/node shadow over nvm.
• Preserved the load-bearing "commands in quantum pairs" section verbatim (the weave wave fails the build if it's removed).

Verification

• pnpm install --frozen-lockfile ✅
• pnpm run docs:build → vitepress build produced 417 HTML pages ✅ (full seal pre-existing red — see above)
• pnpm run docs:dev ✅ — exercised the Quantum Console: ran concept.self.address, ls, and help and saw computed results.
