Subject: [PATCH] fix(cli): use `where` on Windows in commandExists helper

Closes #904

- Replace POSIX-only `command -v` with a cross-platform check:
  use `where` on win32, `command -v` on all other platforms
- Apply the same single-line fix to all three setup utilities:
  local.ts, docker.ts, and railway.ts
