refactor: standardize Node templates on tsdown

[AmanVarshney01]

What changed

• use one shared tsdown configuration for the Minimal, Hono, Elysia, and Nest Node templates
• remove direct esbuild dependencies and shell-specific build commands from generated apps
• emit a single self-contained dist/server.mjs bundle for Composer
• keep Nest's optional integrations external while bundling required runtime dependencies
• declare the Node range required by the generated tsdown version
• leave Deno and framework-native build pipelines unchanged

Why

The raw Node templates performed the same job with separate esbuild command strings. Nest's command also used Unix shell quoting, which breaks under Windows cmd.exe. A shared typed config gives all four templates one portable build path and avoids duplicating build logic.

Composer still owns its internal wrapper build and currently uses esbuild transitively; this change only replaces direct build tooling in generated apps. The existing pnpm allowBuilds.esbuild entry therefore remains intentional.

Verification

• all four raw Node templates generated, installed, emitted their Prisma contract, built to exactly one server.mjs, booted under Node, and returned the expected HTTP status
• actual CLI scaffolds built and booted with Hono/npm, Elysia/pnpm, and Nest/Bun
• Minimal/Bun passed the existing Composer development E2E flow
• all four raw Node templates passed the Windows Server 2025 smoke run: https://github.com/prisma/create-prisma/actions/runs/33414488338/job/99561766311
• bun run check
• bun run typecheck
• bun run test:unit
• bun run build

The expanded Windows workflow was used only for one-off verification and is not part of this PR.

Summary by CodeRabbit

• New Features

  • Updated minimal, Hono, Elysia, and Nest project templates to build with tsdown.
  • Added consistent server bundling configuration and generated build output.
  • Added Node.js version requirements for non-Deno templates.
  • Preserved Deno build behavior in the minimal template.

• Bug Fixes

  • Improved generated project validation, including dependency installation, builds, and server startup checks.

Walkthrough

The PR replaces direct esbuild commands with tsdown for the minimal, Hono, Elysia, and Nest templates. It adds Node.js engine constraints, template-specific entry mapping, shared tsdown configuration, and Nest dependency handling. Tests validate generated files, dependency versions, builds, output bundles, and server responses across supported templates.

Merge Risk: 🔵 Low · up to 22b3a

The PR standardizes generated Node builds on tsdown, but the npm end-to-end scenario installs dependencies with Bun, so npm installation behavior remains unvalidated. The change is otherwise mergeable with explicit owner awareness or follow-up for this bounded verification gap.
