NPC's strength too low to use its starting weapon

[mon-pad]

Describe the bug

An NPC follower has 7 base strength, but the default weapon it was equipped with was a crossbow, requiring 8 strength to use. Despite being unable to use it, when trying to give them a worse weapon it says "My current weapon is better than this".

Steps To Reproduce

Expected behavior

Either for an NPC's default weapon to be one it is capable of using, or for them to accept a worse weapon on the condition that they cannot use their current weapon.

Additional context

[natsirt721]

I've seen this happen with crossbow-wielding bandits too. Makes some of the early bandit-hunting missions very easy when they can't even shoot back.

[inverimus]

This happens quite frequently with the starting NPC having a crossbow and low strength so they can't use it. They also refuse all other weapons that are not better than a crossbow and will continue to wield the crossbow and use it in melee when told not to use ranged weapons.

[actual-nh]

Would weapon_value (in melee.cpp - does both guns and melee weapons) checking meets_stat_requirements (in character.cpp), and returning 0.0 value for not meeting this, fix this for followers, at least? Or is there something more complex than that?
