On Windows (native cmd/PowerShell), process.env.HOME is undefined.
Seven CLI entry points and two library files pass process.env.HOME
directly as homeDir without a cross-platform fallback, causing all
path resolutions to silently fail (resolving to "undefined/.claude/...").
Node.js os.homedir() correctly handles all platforms (HOME on Unix,
USERPROFILE on Windows, OS-level fallback). The project already uses
this pattern in scripts/lib/state-store/index.js and has a getHomeDir()
utility in scripts/lib/utils.js, but it was not applied consistently.
