[FEATURE] Support native/standalone binary installation in devcontainer Dockerfile

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet

Problem Statement

The official devcontainer Dockerfile still installs Claude Code via npm install -g @anthropic-ai/claude-code.

https://github.com/anthropics/claude-code/blob/main/.devcontainer/Dockerfile#L82

However, the setup documentation now lists Native Install as the recommended method, and npm installation is explicitly marked as deprecated.

Proposed Solution

Update the devcontainer Dockerfile to use the native installer:

curl -fsSL https://claude.ai/install.sh | bash

This would also remove the Node.js dependency from the devcontainer, making it usable with non-Node.js base images.
