Adds JMAD.md, a comprehensive guide for users on how to:
1. Create a specialized Google Gemini Gem (BMad Gem) using the team-all.txt prompt from the BMad-METHOD.
2. Configure this Gem to leverage Jules for codebase diagnostics and analysis during planning.
3. Detail the workflow for using the BMad Gem to generate Jules-executable plans for both greenfield and brownfield projects.
The document emphasizes the distinct roles of the BMad Gem (planning) and Jules (execution), and the user's role in relaying information between them. It includes examples of how the Gem should instruct the user to query Jules and how the final plan for Jules should be formatted.
