Note: This task only affects admins.

Feature summary:
When moving a page to a destination that is already a redirect, this message (delete_redirect_and_move_text) appears:

"The destination page "[[:$1]]" already exists as a redirect. Do you want to delete it to make way for the move?"

However, when moving a page to a destination that is already a redirect pointing back to the source page (e.g., moving "Basque Country (autonomous community)" to "Euskadi" when "Euskadi" redirects to "Basque Country (autonomous community)"), it should display an even more specific message, for example:

"You are moving this page to "[[$1]]", which already redirects here. Delete the redirect to complete the move?"

This replaces the generic delete_redirect_and_move_text message in this specific scenario.

Use case(s):

When administrators want to rename a page to what is currently a redirect pointing to it
Common in cases where an article was created under a name that doesn't follow title conventions, or under a title that has become obsolete.

Benefits:

Clearer indication that this is effectively a page rename operation
Reduces admin uncertainty when performing these moves
Distinguishes between overwriting potentially useful redirects (which requires caution) and redirects that will be replaced by the inverse redirect after the move
Makes the interface more intuitive by providing context-specific messaging
