refactor(doctor): use plugin-identity constants for package names

Update doctor checks to use centralized constants from plugin-identity:
- PACKAGE_NAME now references PUBLISHED_PACKAGE_NAME
- System check uses PLUGIN_NAME and LEGACY_PLUGIN_NAME for plugin
  registration validation and legacy name detection
- Formatters updated for consistency
