Subject: [PATCH] ci: add experimental companion firmware build workflow

Triggers on tags matching companion-experimental-* pushed from the
font-experiments branch. Appends -experimental to the version string
so all output filenames are clearly distinguishable from stable builds.
Creates a separate draft release labeled "(Experimental)".

Usage: git tag companion-experimental-v1.x.x && git push origin companion-experimental-v1.x.x
