Add crash reporting (bundle CrashReporter, strip, symbols, upload)

- register plugin + ship Installer/crashreporter.json
- installer bundles the shared CrashReporter (mac pkg + component-plist +
  reporter-scripts promote-if-newer; win .iss shared component) and the JSON
- strip shipped mac binaries; emit dSYM (Xcode) and PDB (/Zi /DEBUG) in Release
- launchCrashReporterOnce() from the processor on first instance
- upload dSYM/PDB symbols to the crash site from release.yaml
- bump to 1.0.33
