A couple of small things

Lycantrophy removes all mithril and adamantium but not orihalcon. Probably an oversight?

Heavenly light indeed works "like alchemist", i.e. does not work on barbarians. Which I suppose could as well be either way. But perhaps that code could be called by mercenaries, for barbarian mercenaries now come with magic weapons. Probably the only way to get magic weapon barbarians?

Heavenly Light is a combat effect for your garrison. It doesn't change what unit gets produced in the city, it only affects battles fought at that city. It does work on Barbarians, but you can only use it to defend your cities.
Yes, Lycanthropy not removing Orihalcon is an oversight. I'll fix it.

Guess I rambled around the point with the second one. Point was that barbarian mercenaries have magic weapons - only barbarians that do and thus stronger than any other barbarian. Which is likely an unintended oddity from changes to alchemy/barbarians. Won't matter in a game, though, as you can only get them rarely by chance. Might be neater if they don't, however.

As for Heavenly light, I get the city defense of course. The magic weapon description is ambiguous for barbs because of the "like alchemist". Probably better to remove that part and just say "gives magic weapons" or "gives magic weapons except for barbarians". I recall heavenly light _not_ giving magic weapons in my latest barbarian game, but I do not have a save anymore so cannot check. If the intention is to give magic weapons to barbs, could be worth a check.

Heavenly light gives the effect of magical weapons only, it does not change the displayed weapon type.
