Smarter craft command parsing — stops at prepositions

- Craft regex captures full text, then parser extracts item name
- Strips filler words (a, an, some, the)
- Stops at prepositions (with, from, using, in, for)
- Takes max 3 words for item name
- "craft sticks with wood" → "sticks"
- "craft a wooden pickaxe" → "wooden_pickaxe"
