Share your fishing setups with other players

When you dial in a great fishing setup, there's currently no way to hand it to a friend or grab someone else's. This adds the ability to export a config profile and import one someone shares with you — pole, bait, buffs, timing, the whole loadout — so a good setup can spread instead of everyone rebuilding it from scratch. Your character-specific pieces (like combat and healing) stay yours; it's the fishing loadout that travels.
