[FEATURE] Complete Offline Installation

Problem Statement

I need to install Claude Code in an air-gapped setting where the host machine doesn't/can't have internet access, but does have an Open-AI compatible LLM endpoint via a local model (example: Qwen3.5 on SGLang)

The problem is:

• The provided documentation only supports internet installation (example: ``curl -fsSL https://claude.ai/install.sh | bash``)
• After installation, CC requires authentication, even for offline settings.

Proposed Solution

Provide a way to download a local (.run file for example), transfer it to an offline machine, and install it there without the need for an active internet connection.
Eliminate the need to sign in for offline settings
