Madxray hacks

Added

• Aimbot (new, Combat) — auto-aims bows, crossbows and tridents at a locked target. Accounts for arrow drop, drag, target movement and your own movement. Options: range, target players/hostile/passive, require clear shot, lead targets, keep lock, aim while idle, aim height, smoothing, player whitelist. Draws the locked target and the predicted arc.
• Schematics folder — <game folder>/madxray/schematics/, created automatically with a README. Reads vanilla .nbt Structure Block files and hand-written .json.
• Stash schematic — ships inside the mod and installs itself on load. Stepped chest hall: double chests terraced up on both sides of a walkway, one item frame per double chest.
• Build Manager screen — pick a build, see the bill of materials against your inventory (green/red per item), rotate it, choose origin, nudge it up/down, Preview, Build/Stop.
• Ghost preview — shows every block and frame before you build, colour-coded (block colour = to do, orange = something in the way, red = missing materials).
• Item frame placement — AutoBuild can now hang frames, not just place blocks.
• MultiAura player safe list — named players never get attacked, overrides everything else.
• Player whitelist editor — shared screen for the above, lists everyone online for one-click adding.

Changed

• AutoBuild rewritten — it now walks to each block and places it one at a time instead of dumping blocks around you. Steps off blocks it's standing on, stands beside walls rather than inside them, swaps blocks out of your inventory into the hotbar, and reproduces block facing (stairs, logs, doors, chests).
• MultiAura — players split out of "hostile" into their own toggle, off by default.
• AutoBuild settings — old single "Structure" cycle button replaced with the Build Manager plus ghost/facing/swap/delay options and a diagnostic log toggle.
