Subject: [PATCH] Use uppercase -GGUF suffix for GGUF export default names
 (#6538)

* Use uppercase -GGUF suffix for GGUF export default names

Match the HF/Unsloth GGUF repo convention (Model-GGUF). Default export save dir
'<model>-gguf' -> '<model>-GGUF', the local-path sibling dir token '_gguf' -> '_GGUF',
and the model-name placeholder 'my-model-gguf' -> 'my-model-GGUF'. Pre-filled defaults
only; no backend/path logic change.

* Keep local GGUF sibling dir lowercase to match backend cleanup

The uppercase change to siblingGgufDirectory diverged from the backend's
hard-coded intermediate '<checkpoint>_gguf' dir (core/export/export.py), which
the export relocates GGUFs out of and then deletes. With the user's save dir
defaulting to '_GGUF', that no-longer-equal lowercase sibling would be relocated
and removed, which can delete an existing export. Revert the sibling default to
'_gguf'; the user-facing GGUF export name (buildRelativeSaveDirectory) keeps the
uppercase -GGUF token.

* Tighten GGUF sibling-dir comment

* Trim comments to be more succinct
