fix: the gap CLI sets bundled files apart

cross_reference printed 20 runtime components bundled with their emulator as [MISSING] and counted them among the files to source. The collection leaves them out by design, as verify and the gaps page already say. They are now listed as [BUNDLED] and counted on their own line.
