[Feature]: Add --skip-install flag to create-xmcp-app CLI for skipping package installation while still writing dependencies

[0xKoller]

Problem statement

Right now npx create-xmcp-app@latest always runs the package manager install step automatically. There is no way to skip it.

This is inconvenient in several common cases:

• Monorepos (conflicts with workspace install logic)
• Offline setups or custom package manager workflows
• CI/CD pipelines that want to control installation separately
• Quick scaffolding + manual install later

Proposed solution

Add a --skip-install flag:

npx create-xmcp-app@latest --skip-install

This way, it still creates all project files and writes a complete package.json with the required dependencies (xmcp, @xmcp-dev/cli, etc.), but skips running any install command.
