Summary20630: Renaming a parent custom theme breaks child theme inheritance and leaves stale parent references
Description

When a custom theme that serves as the parent of another custom theme is renamed, any child themes that extend it continue to reference the original parent theme internally, even though the Theme Editor overview displays the parent's new name.

As a result, the child theme can no longer resolve inherited assets and becomes unusable in the Theme Editor. Attempting to edit, duplicate, extend, or reinstall the child theme results in errors indicating that inherited files or the parent theme cannot be found, even though the parent theme still exists under its new name.

Steps To Reproduce

Steps to reproduce

  1. Create a custom theme (ParentTheme) extending fruity_twentythree.
  2. Create a second custom theme (ChildTheme) extending ParentTheme.
  3. Rename ParentTheme using the Theme Editor.
  4. Attempt to edit, duplicate, extend, or reinstall ChildTheme.

Expected result

Renaming a parent theme should either:

update the parent (extends) references of all dependent child themes automatically, or
prevent renaming while dependent themes exist, or
present a clear validation message indicating that renaming the parent theme will invalidate dependent themes.

Actual result

The child theme cannot resolve its parent and errors such as the following are displayed:

Theme 'ChildTheme' was not found, can't find file: ./css/variations/theme_apple.css

Step to reproduce 4 still can be partially fulfilled.
If the child theme ('child') is uninstalled and the parent theme ('parent') changes name (e.g. to 'parent_renamed'), child theme can't be reinstalled.
The name of the parent doesn't change in the "Extends" column of the deinstalled themes table (stays 'parent' instead of changing to 'parent_renamed').

Error message:
"You can't import the theme 'child' because 'parent' is not installed."
