Fix start.bat (ASCII-only, guaranteed window stays open) + add start.ps1
- start.bat: remove all Chinese characters (caused silent failure when Windows batch parser ran before chcp 65001 took effect); add :error label so window stays open with pause on any failure - start.ps1: PowerShell alternative launcher with coloured output, works without worrying about cmd.exe encoding issues Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>
