feat(cli): support compute app regions

[AmanVarshney01]

Summary

• adds prisma-cli app deploy --region <region> for new app creation
• reads typed region defaults from prisma.compute.ts through @prisma/compute-sdk@0.31.0
• keeps existing apps in their current region; explicit --region mismatches fail with a usage error
• documents deploy-all behavior and rejects --region as a per-app flag for bare multi-app deploys

Examples

import { defineComputeConfig } from \"@prisma/compute-sdk/config\";

export default defineComputeConfig({
  region: \"us-west-1\",
  apps: {
    api: { root: \"apps/api\", framework: \"hono\" },
    web: { root: \"apps/web\", framework: \"nextjs\", region: \"eu-west-3\" },
  },
});

prisma-cli app deploy --app my-app --region us-west-1
prisma-cli app deploy api

region only applies when deploy creates a new app. Existing apps are not moved between regions.

Testing

• pnpm --filter @prisma/cli test
• pnpm --recursive exec tsc --noEmit
• pnpm lint

Summary by CodeRabbit

• New Features
  • app deploy now supports a --region option for newly created apps.
  • Deployment examples and help text now include region usage.
• Bug Fixes
  • Existing apps keep their current region during deploys.
  • Deploying with a region that conflicts with an existing app now returns a clear usage error.
  • Multi-target deploys now reject per-app region overrides.
• Documentation
  • Updated product docs to clarify how app regions are selected and when defaults apply.

Walkthrough

Updated the public docs and CLI for app deploy to add --region. Compute deploy input merging now carries region, deploy-all argv generation includes region per app, and controller logic normalizes, validates, and propagates region for app creation while preserving existing app regions. Tests were added for help text, CLI parsing, input merging, deploy planning, and region conflict cases.
