Summary

• Pass the SimLoop version from project.version in build.gradle to the MkDocs build.
• Use MkDocs' !ENV tag to populate the documentation footer dynamically.
• Remove the redundant version check task.
• Update PUBLISHING.md to reflect the new release process.

The documentation footer now uses the version declared in SimLoop/build.gradle, eliminating the need to maintain a duplicate version in mkdocs.yml.

Verification

The docsSite task supplies the footer value directly to MkDocs, so changing the Gradle version updates the generated pages automatically.

Closes #16

Implemented the documentation footer version change. The Gradle build now supplies the version directly to MkDocs, and the publishing instructions have been updated to match. The duplicate version declaration and the old mismatch check have been removed.
