Problem: selection_hashes split the Selection on every comma before
stripping quotes, so a name containing a comma (Blender allows a material
called `Green, Glossy`) was cut into two names that match nothing, quoted
or not; only its `<hex>` hash selected it.
Fix: a small tokenizer splits at commas outside quotes. A name in double
or single quotes stays whole, a backslash takes the next character
literally (`Green\, Glossy`), and unquoted lists, wildcards and `<hex>`
hashes parse as before. The CPU effect and the GPU path share the function.
