Subject: [PATCH] Make next_token static to avoid global symbol collisions

next_token was the only internal helper without static and is not in
tinyexpr.h. Linking against another TU that defines next_token can
silently bind the wrong function under --allow-multiple-definition or
LD_PRELOAD. Fixes accidental export; see issue discussion.
