Spawn Detective

v0.1.0-alpha.4

Fixed

• Peaceful no longer reads as a blanket "nothing spawns here". Asking about a chicken on Peaceful answered "CHICKEN IS BLOCKED RIGHT NOW - Difficulty: peaceful", in a swamp that was still full of chickens. Peaceful removes the hostile categories from the spawn tick and leaves every other one running normally, so the difficulty row is now allowed to answer only for the mobs it actually stops. It still shows on the world list, where it belongs, and reads n/a beside a mob it has no say over.
• A monster on Peaceful is no longer told its problem is permanent. The report answered a zombie with "cannot spawn here - the mob's own spawn rules", listing light, block below and biome as leads. None of that had been measured: Peaceful short-circuits the mob's spawn predicate before the position is looked at, so every roll fails whatever the spot is like. The report now says so and names the difficulty, which is a setting one command reverts, not a fault in the block.
