Nova Mekanism

Added — rare-material replication

• Matter Replicator (5×5×5 containment sphere): dissolve a rare artefact with a blank matter pattern in the Large Chemical Reactor — the artefact is destroyed and its structure is imprinted onto the pattern. Install that pattern (never consumed) and feed primordial matter, and every run rolls a chance at a copy: nether star 40%, dragon egg 20%, chaos shard 25%, Gaia spirit 40%. Every run also yields exotic residue, which the reactor turns back into feedstock — a closed GT-style loop that still needs a steady antimatter and stellar-matter supply.
• GT-style chance outputs. Recipes can now roll an extra product; the machine waits instead of running when the output slots are full, so a rare roll is never voided. JEI shows the chance slot with its odds.

Changed — deeper end-game chains

• Neutronium is now a 4-step chain (was one fusion recipe): naquadria → degenerate matter (fusion) → neutron-rich mass (centrifuge) → molten neutronium (alloy blast furnace) → neutronium (vacuum freezer).
• Stellar cores need distilling first: molten stellar matter → stellar plasma (distillation tower) → stellar core (freezer). Both steps shed stellar ash, which the reactor re-ignites into molten stellar matter.
• Trans-dimensional metal is a 2-step chain: the stabilizer now sheds singularity fragments, which only stabilise once dissolved in primordial matter — linking the black-hole line into the replication line.
• Most machine controllers moved to the Assembly Line (14 of them), each behind its own research: petrochemistry, digital logic, particle physics, antimatter engineering, matter replication and arcane engineering, plus cryogenics and metallurgy. The foundation machines (blast furnace, reactor, distillation, mixer, electrolyzer, centrifuge, alloy blast furnace, vacuum freezer) and the circuit assembler / research station / assembly line stay on the crafting grid — the ABF and freezer supply the molten alloy every assembly-line recipe is soldered with.
• Zinc ore and Extra Super Duralumin (7075) added and worked into several multiblock and intermediate recipes.
• Graviton coil (tier 5, above antimatter) and graviton alloy added; the trans-dimensional alloy now requires the new coil.

Fixed

• Matter replicator built and previewed as a box in JEI and the construction terminal while its validator required a sphere — the structure could never be formed from the shown plan.
• Pattern imprinting was unreachable. Every imprint recipe took a blank pattern plus exotic plasma and differed only in volume, so the cheapest always won and only nether-star patterns could ever be made.
• Recipes could shadow each other. Machines pick the first recipe they can satisfy, so a broader recipe hid narrower ones — the naquadria fusion step and the tier-3 netherite-ingot smelt were both unreachable. Matching now runs most-specific-first (and prefers the best recipe the installed coil allows), and a startup audit reports any recipe that is still unreachable.
• Chance outputs were produced but never shown in JEI, and their odds label could overlap the gas output slot.
• Three new gases displayed their raw translation keys (wrong key prefix).
