Reviewer's Guide

Updates the documentation navigation configuration by removing links in zensical.toml that point to deleted stub markdown pages so the docs build reflects only existing content.

**suggestion:** Consider removing the empty "Tutorial" section or adding at least one entry to avoid an empty nav group.

With `"Data Analysis"` and `"Simulations"` removed, `"Tutorial"` is now an empty array. Depending on the docs theme, this may render as a blank or non-clickable sidebar section. To avoid a confusing nav entry, either drop the `"Tutorial"` group until content exists or add at least one child item.

Code Review

This pull request removes the 'Data Analysis' and 'Simulations' entries from the 'Tutorial' navigation group in the documentation configuration. Feedback suggests that the entire 'Tutorial' block should be removed to avoid displaying an empty section in the documentation user interface.

docs/zensical.toml (11-12)

The removal of these entries leaves the Tutorial navigation group empty. To maintain a clean documentation structure and avoid displaying an empty section in the UI, the entire Tutorial block should be removed from the nav array.
