A deliberate standalone commit, as AGENTS.md asks for this file.
Content is byte-identical -- 2255 mappings, not one changed -- which is the
point: it demonstrates the rewritten mkcontrollermappings.sh produces exactly
what the old one did on the success path. The only differences are the $(date)
stamp and the include guard, which is _AKGL_SDL_GAMECONTROLLERDB_H_ now so it
matches every other header in include/akgl/.
That rename was made in the generator rather than by hand, per the rule about
generated files, and the tracked copy carries it so the next regeneration shows
no spurious diff.
