Pull request overview

Updates Python plugin code to compile against the updated platform APIs (localization + read-action requirements), while keeping behavior the same.

Changes:

• Migrate live template macros’ getPresentableName() to return LocalizeValue and add @RequiredReadAction where PSI is accessed.
• Update exit-point highlighting handler to use CodeInsightLocalize and add @RequiredReadAction annotations.
• Apply minor modernization/formatting (e.g., generics diamond, pattern matching instanceof).

calculateResult can return null (e.g., when params.length != 1 or paramResult == null), but the override isn't annotated as nullable. Consider adding @Nullable (and importing it if needed) to match the other macros in this package and keep nullability analysis accurate.
