Summary

SUMMARY: Content "Expand metalworking and other older proficiencies"

Purpose of change

Continuing to add proficiencies. Blacksmithing and knapping are the OG demo proficiencies, and need to be brought to speed to match the rest of the proficiencies that have been added.

Describe the solution

• Adds a metalworking proficiency that is easy to learn, and prerequisite for blacksmithing and most other basic metal shaping proficiencies. When it's possible to learn proficiencies from books and select them at the start, we should consider making this one impossible to learn by trial-and-error. For now, given how critically important it is for many gameplay options, this should wait for those systems.
• Adds a second knapping proficiency, and makes the first one a "principles of knapping" version that is hard to figure out. The second represents speed from experience.
• Adds a toolsmithing proficiency that, loosely, is for "things that should be durable for reuse".
• Adds a basic and advanced welding proficiency and implements them in recipe_other and parts.json
• Adds a plumbing proficiency. It's barely used currently but I had to do something about the water faucet recipe.
• Audits a few autolearn and time to craft details as well as some activity levels that were a bit high.

Describe alternatives you've considered

As often happens, i wound up with too much going on in this PR, because on a deep read of recipes so much stuff comes up. in the future I think I'm going to try to focus on getting a single recipe file correct rather than working on a single category of proficiencies.

You might also want to make repair require these new proficiencies. I have made an issue with my thoughts on repair and mending, which may be applicable. #44480

That will be outside this PR but yes, repair should definitely use proficiencies as well. I am open to someone making a PR like that...

[I-am-Erk]

I will leave this up for review for a day or so, and then if no comments, will merge it myself as this is a big project and other things are depending on this.

I'm not sure about making things like metalworking impossible to learn on your own: back in the day, books weren't exactly common, and many blacksmiths were probably illiterate. Though they may have learned through a master-apprentice relationship. So maybe learning through trial-and-error is slow, but much faster with an NPC giving you lessons. And I'm assuming reading a book isn't enough to develop the intuition and muscle memory required for certain tasks.
