Adventure: !adventure recipes — list known crafting recipes

Players had no way to see what they could craft without grinding
ingredients and watching combat narrative. New command lists every recipe
unlocked at the player's current Foraging level, grouped by tier, with:

- Result name + ingredient list (so players know what to gather)
- Per-recipe success rate at the player's current level
- Locked-recipe count + next-unlock threshold
- Max auto-crafts per combat (1 + (level-10)/10)

Sub-Foraging-10 players see only the unlock hint.
