@JamieSinn what's this change for?

[JamieSinn]

this is mostly just an arch update for docs - eventually we'll clean them up to show the full flow since the old one is out of date

• Fixed SVG fill attribute values from "transparent" to "none" in existing diagrams (server-sdk-initialization, event-manager, config-manager)
• Updated GitHub Actions workflow to use a pinned commit SHA instead of @main branch reference

The GitHub Action reference has been pinned to a specific commit SHA (2e381afb2bae7e169b76bfb068e8d8b2089106ee) instead of using @main. While this improves reproducibility, it's important to verify that this commit hash exists and is from a trusted source. Consider documenting why this specific commit was chosen or periodically reviewing and updating to newer versions for security patches and bug fixes.
