1.2.1 — Datagen correctness sweep (mineable + loot drift fixes)

Fixes

• Unmineable blocks / no "correct tool" tick: the shipping data/minecraft/tags/block/mineable/pickaxe.json was hand-written and had drifted from the block registry (its contents were overwritten during the 1.2 anvil work), so hematite ore plus ~30 other blocks broke without dropping and showed no pickaxe check-mark in Jade/WTHIT. The minecraft:mineable/{pickaxe,shovel,axe} and needs_{stone,iron}_tool tags are now generated from the block registry (MagBlockTagsProvider) instead of hand-listed, so a newly-added block can no longer be silently left out. Deleted the stale hand-written tool tags.
• Several machines dropped nothing when broken: barkhausen_generator, emp_charge, gyrostabilizer, induction_pad, kinetic_coil, magnetic_item_frame, and magnetostrictive_sensor had no loot table at all (and weren't in the loot provider's known-block list, so datagen never warned). Block loot is now registry-driven: any block without an explicit table drops itself, and the known-block set is derived from the registry, so a future missing table fails runData loudly instead of shipping undroppable. Also migrated 12 plain drop-self loot tables that were hand-written in src/main (the anvils, MHD jet, micro-thruster, solar sail, homopolar motor, structural inducer, tokamak coil/controller, g-force cushion) into datagen.

Recipes

• Deuterium Oxide now also has smelting and blasting recipes — a bucket of water cooks into a bucket of deuterium oxide (heavy water), alongside the existing glowstone-irradiation craft.

Internal / dev tooling

• Sodium + Iris now load in dev: Sodium's Modrinth NeoForge jar is a self-loading JarJar wrapper that doesn't unpack on the dev flat classpath, so Iris was crashing runClient on missing Sodium API classes. build.gradle now unwraps and merges it into a single dev mod jar (plus its fabric-renderer shims) so runClient launches with shaders. Sodium/Iris remain localRuntime-only soft deps — neither ships.
• Dev test-mod bumps (all localRuntime, none shipped): Supplementaries 3.6.8 + Moonlight 3.0.18 (older builds' Sodium-compat mixin hard-crashed world load once real Sodium 0.8 loaded), Create Crafts & Additions 1.6.0, Immersive Aircraft 1.4.6, Sophisticated Core 1.4.59, Sophisticated Storage 1.5.60, Spartan Weaponry Unofficial 1.2.1, GuideME 21.1.16, and Create: New Age 1.2.0 — the last forces CC:Tweaked to 1.116.2 (an optional Maven transitive of aeronautics + simulated) to satisfy New Age's optional dependency range.
