🔨 Bugfixes

• NPM binary install integrity — Fixed a race/corruption scenario where Stacktape could run with a partially extracted bin directory and fail with missing helper-lambda ZIP files
• Helper lambda availability checks — Launcher now validates required helper-lambda artifacts before reusing cached binaries
• Global binary safety check — Global binary shortcut now verifies helper-lambda artifacts before execution, preventing invalid cache reuse

✨ Improvements

• Race-safe installation — Added installation lock handling to avoid concurrent extraction conflicts on first run
• Self-healing cache behavior — Added install marker validation and automatic cleanup/reinstall for incomplete cache states
• Resilient bootstrap flow — Added retry path for failed/partial installs to improve reliability across CI and local environments
