mux: single source of truth for the version label (VERSION_LABEL/MUX_APP)

Browse Source 
The CLI --version, the MKV muxing/writing-application field, and the FVI generator
all derive from one libfreemkv const, so a binary reports the exact same label it
stamps into the files it produces — no split-brain where an MKV claims one version
and the binary another.
