Here is a concise summary of the pull request changes:

Summary: The pull request updates the architecture diagram in README.md, providing a clearer and more detailed view of the Kepler Exporter project's components. The new Mermaid diagram includes additional elements, such as eBPF program and ML features, and highlights subsystems with distinct colors and class definitions, enhancing readability and understanding of the project's architecture.

Key Modifications:

• Updated architecture diagram in README.md
• Added new elements, including eBPF program, process/container/VM info, hardware power readings, ML features, and idle/dynamic energy attribution
• Improved diagram readability and understanding of the project's architecture

Impact: This change enhances the project's documentation without introducing functional changes, making it easier for developers to understand the system's components and their interactions.

Observations/Suggestions: The deduplication of changesets is appreciated, as it reduces redundancy and makes the review process more efficient. The updated diagram is a valuable addition to the project's documentation, and it would be beneficial to consider adding a brief description or legend to explain the colors and class definitions used in the diagram.
