feat: add minimal Turborepo setup

[anthonyshew]

Note

This is a starting point. The Turborepo configuration is correct, but some package scripts need fixes (the issues are easily visible when running tasks like pnpm lint or pnpm test).

Summary

• Adds Turborepo for monorepo task orchestration
• Enables parallel task execution and caching across apps/frontend and apps/backend
• Uses pnpm workspaces

Files Added

File	Purpose
package.json	Root workspace config with turbo scripts
pnpm-workspace.yaml	Defines workspace packages
turbo.json	Task pipeline configuration
apps/backend/package.json	Wrapper scripts to run Python tasks via uv
pnpm-lock.yaml	Lockfile

Available Commands

pnpm dev              # Run both frontend + backend
pnpm dev:frontend     # Next.js only
pnpm dev:backend      # FastAPI only
pnpm build            # Build all packages
pnpm lint             # Lint all packages
pnpm test             # Test all packages

Summary by cubic

Adds a minimal Turborepo setup with pnpm workspaces to orchestrate tasks across frontend and backend. Lets you run, build, lint, and test apps together with parallel execution and shared caching.

• New Features

  • Turborepo pipeline (turbo.json) for build, dev, lint, format, and test.
  • Root scripts to run tasks across the monorepo and per app via filters.
  • Workspace setup (.gitignore update, pnpm-workspace.yaml, lockfile).
  • Backend scripts use uv for FastAPI dev and pytest.

• Migration

  • Requires pnpm 9.15.4.
  • Run pnpm install, then pnpm dev. Per app: pnpm dev:frontend or pnpm dev:backend.
  • Some package lint/test scripts need follow-up fixes; expect errors for those tasks.

^{Written for commit 84a34c0. Summary will update on new commits.}

Hey @anthonyshew I'm using npm on this project right now. Also, right now, there's another PR that fixes some issues on the front-end.
