Update AWS icon assets and documentation

[thealiflab]

• Added CLAUDE.md to .gitignore.
• Revised IMPORT_STEPS.md to clarify SVG extraction and layout conventions for AWS icons.
• Updated SOURCE.md with the latest verification date and details on the new icon set structure.
• Modified several SVG files to remove gradient definitions and apply a solid fill color.
• Deleted the obsolete Data-Pipeline.svg file.
• Adjusted various SVG files to ensure consistency in structure and styling.

These changes enhance the clarity and usability of the AWS icon assets.

Hi Developer,

I was excited to discover this open-source diagramming tool. Our team currently uses multiple platforms such as AWS in Miro and FigJam for architecture and workflow diagrams, so this project is extremely valuable for simplifying and standardizing our AWS diagram workflows.

While using the project, I noticed that several AWS icons were outdated. This pull request updates the icons to the latest versions. I followed the existing processing approach used in the repository and verified the changes thoroughly in my local environment, including validation with Claude Code.

Thank you for building and maintaining such a useful project. I am looking forward to your feedback and would be happy to contribute further in the future. Once these updates are merged, I plan to share the tool with my team as a strong alternative to relying on Miro Business Premium for diagram creation.

Thanks again for the great work.

Hi, thanks so much for this, and for the kind words!

I reviewed the PR and it looks great. The icon updates are clean, the shape-ID rename is consistent across the code, and all the affected tests pass on my end. I really appreciate that you followed the existing processing approach — made it easy to review.

Merging now. Thanks again for the thoughtful contribution, and that's awesome to hear about your team — would love to have you contribute more down the line. 🙌

If you have any feedback on the project, what's working, what's missing, anything that'd make it more useful for your AWS workflows, please feel free to share it. Always happy to hear it.
