Subject: [PATCH] fix(resolver): strip all dashes when matching container names

Instead of prefix matching on the part before the first dash, now strip
all dashes from both the lookup name and the stored container/selector
names and compare exactly. This improves matching accuracy for names
containing multiple dashes or dashes in varying positions.
