Homebrew cask not available on Linux - consider adding a formula

Summary

The claude-code Homebrew cask is only available on macOS, as Homebrew casks are macOS-specific (they handle .dmg, .app bundles, etc.). When attempting to search the cask via Homebrew on Linux, users encounter:

╰─❯ brew search --cask claude                                                                                ─╯
[12:31:21] ➜ brew search --cask claude
Error: No formulae or casks found for "claude".

Current Workaround

Linux users must use the native installer:

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

Feature Request

Consider adding a Homebrew formula (not cask) for Linux support. This would:

• Provide a consistent installation experience across macOS and Linux
• Allow Linux users to manage Claude Code through Homebrew like other CLI tools
• Enable easy updates via brew upgrade claude-code

Examples

Many CLI tools provide both:

• A cask for macOS: brew install --cask tool-name
• A formula for Linux: brew install tool-name

Additional Context

• macOS cask: https://formulae.brew.sh/cask/claude-code
• Requirements listed: "macOS >= 10.15"
• Supported Linux distros: Ubuntu 20.04+, Debian 10+

This would improve the developer experience for Linux users who already use Homebrew as their primary package manager.
