Add NoRules Disabler - #9052

Thanks for the PR! A few things a reviewer will likely flag:

• Mappings/imports won't compile as-is. The codebase is on Yarn mappings, so this needs net.minecraft.network.packet.c2s.play.PlayerMoveC2SPacket (.PositionAndOnGround / .Full) and onGround rather than the Mojang-mapped ServerboundMovePlayerPacket/isOnGround. network also isn't imported here.
• Rotations are dropped globally while enabled. Every outgoing PosRot is replaced with a rotation-less Pos, so nothing rotation-dependent (KillAura, Scaffold, block interaction) reports a yaw/pitch to the server any more. LookAndOnGround also still goes through untouched, so the packet stream ends up inconsistent. Worth explaining why that's the intended behaviour for this target.
• The PR body doesn't say what "NoRules" is — which network/anticheat, and how the bypass was verified. Other disabler entries are tied to a concrete target, and most gate themselves on the relevant conditions instead of running unconditionally.
• Docs impact: new Disabler entries should get a row on the Disabler page in the Documentation repo.
