Problem:
- Install wizard on macOS failed with "Homebrew not found" when user
didn't have Homebrew installed, blocking Claude Code installation entirely
Fix (electron/main.ts):
- Add fallback: when Homebrew is not found, download official Node.js v22.12.0
binary tarball from nodejs.org and extract to ~/.codepilot/node/
- No Homebrew or sudo required — curl + tar only
- Detects architecture (arm64/x64) via process.arch
- Add ~/.codepilot/node/bin to getExpandedShellPath() so the downloaded
Node.js is found by subsequent install steps and server launcher
Install flow now: Homebrew found → brew install node (existing)
Homebrew missing → download tarball to ~/.codepilot/node/ (new)
