/**
 * Homedir guard for destructive commands (init, uninstall).
 *
 * Running `trellis init` / `trellis uninstall` in `$HOME` is catastrophic:
 * platforms like Claude Code, Codex, OpenCode all store global runtime data
 * (`.claude/projects/<sanitized-cwd>/*.jsonl` chat history, `.codex/sessions/`,
 * `.opencode/` caches, etc.) directly in the user's home directory. If
 * trellis manages the same `.{platform}/` config dirs and the hash manifest
 * picks up runtime data, uninstall would later unlink it.
 *
 * Subdirectories of home (`~/Documents/projects/foo/`) are NOT blocked — only
 * exact-home match.
 *
 * Bypass: `TRELLIS_ALLOW_HOMEDIR=1`.

/**
 * Returns true if `process.cwd()` is exactly the user's home directory.
 *
 * Uses `realpathSync.native()` on both sides so symlinks, `..` segments, and
 * case differences (Windows) don't confuse the comparison. On Windows the
 * comparison is also case-insensitive — `C:\Users\Alice` matches
 * `c:\users\alice`.
 *
 * Permissive on lookup failure: if realpath fails for any reason (broken
 * symlink, EACCES, etc.) we return false so a safety check doesn't crash
 * the command.
