feat(module): restore XRay with true see-through terrain patch [Release]

Restore the full XRay ore-scanner module (flood-fill vein detection,
anti-fake-ore scoring, packet-driven blind scan, wireframe ESP boxes and
on-screen tracers, ~27 settings) and add BlockPatch, which hooks
Block.shouldRenderFace so terrain turns transparent and only the target
ores render while XRay is enabled. Use @EqualsAndHashCode for BlockKey.

Closes #34

+/**
+ * "True XRay" terrain patch.
+ *
+ * <p>{@code Block.shouldRenderFace} is the vanilla face-culling decision evaluated for every block
+ * face while chunk meshes are built. We hook it at HEAD: when the {@link XRay} module is enabled we
+ * force the result so that only XRay target blocks render (all faces, hence visible through walls)
+ * and every other block renders no faces at all (it becomes invisible). When XRay is disabled we
+ * fall through untouched, leaving vanilla culling intact.
+ *
+ * <p>Toggling the module calls {@code mc.levelRenderer.allChanged()} (see {@link XRay#onEnable()}/
+ * {@link XRay#onDisable()}), which rebuilds every chunk mesh so this decision is re-evaluated and
+ * the effect applies/clears immediately.
+ *
+ * <p>The mojmap {@code method}/{@code desc} below are remapped to the runtime SRG name
+ * ({@code m_152444_}) by {@code Bootstrap.remapMethod}, exactly like the other patches.
