Auto-update export filepath when collection is renamed

[Weisl]

Feature

When a collection is renamed in the Blender outliner, the export filepath is now automatically updated to reflect the new name — keeping the directory and file extension unchanged.

Example: Renaming MyMesh → CharacterMesh with prefix SM_ changes the path from //export/SM_MyMesh.fbx to //export/SM_CharacterMesh.fbx instantly.

Behavior

• Only the filename portion of the path is updated; the export folder and extension are preserved.
• Paths that were manually customized (i.e. don't match the collection name + current prefix/suffix pattern) are left untouched.
• The feature is on by default and can be disabled in Preferences → UI → Behavior → Auto-Update Path on Rename.

Release Notes Highlight

Export filepaths now stay in sync automatically when you rename a collection. No more needing to manually run "Fix Export Filename" after a rename. The behavior can be turned off in addon preferences.
