Add claude-code-wsl2-setup to Tools & Utilities

[congmnguyen]

Adds claude-code-wsl2-setup, an MIT-licensed collection of documentation and install scripts for running Claude Code on WSL2 + Windows Terminal.

It documents WSL2-specific friction and how to fix each piece:

• Screenshot paste — Go daemon (wsl-screenshot-cli) polls the Windows clipboard so paste returns a WSL file path in Claude Code or Codex
• Balloon-tip Windows notifications fired from WSL via PowerShell on Stop and PermissionRequest hooks, auto-suppressed when Windows Terminal is focused
• LSP plugin wiring for the four official language servers (TS, Python, Go, Rust)
• Custom statusline (project dir · context bar · 5h / weekly usage)
• Voice mode (ALSA → PulseAudio → WSLg socket)
• Smaller fixes: Shift+Enter newline, BROWSER env var for OAuth, MCP server install commands

Each fix is a standalone markdown doc with the problem, root cause, and exact config. The repo's CLAUDE.md is structured so Claude Code itself can apply the setup end-to-end: clone, run claude, prompt "Set this up".

Inserted at the end of 🛠️ Tools & Utilities following the existing format for entries without star counts yet.
