Image default is beam 5 on x86 (1 on ARM). Benchmarked on framework-pt
(i5-1135G7, base-int8, real speech): beam 1 transcribes identical text
~45% faster; extra CPU threads made it slower, so only the beam changes.
App revision 3.4.2 > image 3.4.1 so catalog-driven nodes roll the args
change; a 3.4.1-1 suffix would semver-compare LOWER and never ship.
