0.33.1 — Instant TUI & Browser Launcher Fix

Fixed: CLI Default Command Execution (kandown) — fixed bin/tui.js path resolution in global installation so running kandown with no arguments instantly opens both the browser AND the interactive terminal board UI (TUI), eliminating the fallback message Open kandown.html in browser.
Fixed: Automatic Browser Launch — kandown now automatically invokes open (macOS), xdg-open (Linux), or start (Windows) on launch unless --no-open is specified.
