chore(01-02): add prerequisite plugin structure

Browse Source 
- Create main singleton class
- Create activator with version checks
- Create deactivator with rewrite flush
- Update main file to include core classes

This is a blocking fix (Rule 3) - Plan 01-01 was not completed but
these files are required for Plan 01-02 to execute.
