enhancement: add Node.js and framework version selection (Express, Next.js, NestJS)

[marcosgdz03]

Context

Node.js project generation supports:

• Express
• NestJS
• Next.js :contentReference[oaicite:2]{index=2}

But currently:

• No Node.js version selection
• No framework version control

Goal

Add full version management for Node.js ecosystem during project creation.

Functional Requirements

• Select:
  • Node.js version (16, 18, 20 LTS)
  • Framework (Express, Next.js, NestJS)
  • Framework version
• Generate:
  • package.json with exact versions
• Optional:
  • .nvmrc file
  • engines field in package.json

UX/UI

• Extend existing QuickPick flow
• Show LTS recommendations
• Warn about incompatibilities (e.g., Next.js vs Node version)

Technical Considerations

• Fetch versions from npm registry
• Cache version metadata
• Keep compatibility with current generator structure

Acceptance Criteria

• Users can select Node.js + framework versions
• package.json reflects selected versions
• Project runs correctly after generation
