feat(node): support TanStack Start builds

[iloveitaly]

Motivation

TanStack Start applications were being treated as static Vite SPAs, resulting in incorrect build plans and no reliable production server command. This adds framework-aware detection and server fallback support for deployable TanStack Start applications.

Description

• Detect @tanstack/react-start applications and exclude them from static Vite builds.
• Use srvx as a fallback server when no start script is defined.
• Document TanStack Start build behavior and Nitro recommendations.
• Add a representative TanStack Start example project.
• Support absolute URLs in logger documentation suggestions.

Test

• Node provider tests cover TanStack Start detection, Vite exclusion, dependency classification, and fallback command selection.
• Example build-plan coverage validates the generated TanStack Start plan.
