"""Regression: a DPT-5.001 shutter position feedback named "… RM" (Rückmeldung,
the German-market status abbreviation) must be recognised as the cover's position
STATUS — not misclassified as a standalone lighting/light entity (issue #12, field
data by Kris1166).

Two layers were broken and are both covered here:
  * classification — the RM GA sits in a shutter ETS Function (blank role) but a
    bare DPT 5.001 with no shutter keyword fell to the lighting default; Function
    membership now promotes it to `shutter`;
  * status recognition — "RM"/"FB" is a whole trailing token the substring
    keywords ("rm "/"rm_") and the stopword tokenizer both dropped, so it read as
    a command; `name_is_status` now recognises it, so it wires as the cover's
    `position_state_address` (a status), never a `position_address` (a command).

Negative guard: a genuine LIGHT brightness feedback named "… RM" that is NOT in a
shutter Function must stay `light` — the promotion is Function-scoped, not a
blanket "RM ⇒ shutter".
