Is your feature request related to a problem?

I'd like to know which charm mods are good on my build, and would like the "Trade for these items" functionality to calculate stat weights on the charm mods for me.

Describe the solution you'd like

The "Trade for these items" should include an option to search and calculate the weights of the new charm item type when selecting a jewel slot, similar to base/abyss jewels.

Describe alternatives you've considered

No response

Additional context

I've tried adding the functionality myself by adding a new option to the TradeQuery that had category tags like "animal_charm" and "str_animal_charm" etc, but when searching, I got the error message "Could not find mods" and I'm not experienced enough to do this myself unfortunately

Start by tracing the TradeQuery system's existing stat-weight calculation for base and abyss jewels, then compare how charm item types and their mod categories are represented. Confirm the expected search path for a jewel slot and reproduce the "Could not find mods" error; done means charm searches calculate and return weights without breaking existing jewel searches.
