BUG: Fix check for orphaned remote modules

[SimonRit]

Some remote modules have a repository name which does not match the .remote.cmake file name. A few start with ITK, SCIFIO is named scifio-imageio, WebAssemblyInterface is named ITK-Wasm.

I used the following bash command line in Modules/Remote to check the list of exceptions:

for i in *remote.cmake ; do if ! test -e $(grep GIT_REPOSITORY $i | sed "s/.*\\///g" | sed "s/.git//g" | sed "s/^ITK//g").remote.cmake ; then echo $i ; fi ; done

Greptile Summary

This PR updates itkCheckForOrphanedRemoteModules.cmake to correctly handle remote modules whose cloned directory name does not match their .remote.cmake file name. Previously, the check assumed a direct name correspondence; now it strips the ITK prefix from cloned directory names before looking up the cmake file, and adds explicit exceptions for directories that require completely different names (scifio-imageio clones → SCIFIO.remote.cmake, ITK-Wasm clones → WebAssemblyInterface.remote.cmake).

• Adds string(REGEX REPLACE "^ITK" "" ...) to strip the ITK prefix from directory names, enabling the check to find cmake files like BioCell.remote.cmake for a directory named ITKBioCell.
• Introduces an explicit exception list (Deprecated, ITK-Wasm, scifio-imageio) to skip directories whose names differ too much from their cmake file names even after the prefix strip.

Confidence Score: 4/5

The scifio-imageio fix is correct and merges cleanly, but the ITK-Wasm exception remains unreachable after the prefix-strip mutation — a concern already raised in review discussion that has not been fully resolved in the current revision.

The scifio-imageio exception correctly catches clones of scifio/scifio-imageio.git before the file-existence check. However, the ^ITK regex turns an ITK-Wasm directory into -Wasm, so the STREQUAL "ITK-Wasm" guard is never entered; a developer with that module checked out would still hit FATAL_ERROR.

CMake/itkCheckForOrphanedRemoteModules.cmake — specifically the interaction between the prefix-strip regex and the ITK-Wasm exception string.

Important Files Changed

Filename	Overview
CMake/itkCheckForOrphanedRemoteModules.cmake	Adds ITK prefix stripping and an exception list for modules with mismatched directory/cmake names; the scifio-imageio exception is correct, but the ITK-Wasm exception string does not match the stripped name (-Wasm vs ITK-Wasm), a bug flagged in a prior review thread.
