Fix command prefixes and remove plugin README

Two corrections based on feedback:

1. Remove plugin README - only the marketplace README is needed
2. Update all command references to use correct prefix format:
   - /plan → /compounding-engineering:plan
   - /work → /compounding-engineering:work
   - /review → /compounding-engineering:review
   - All other commands updated similarly

This ensures the documentation accurately reflects how users actually invoke the commands.
