Add the modules Truly Modular is missing, and two more materials

Platinum (Create Propulsion: Simulated) and aviation alloy (AeroEngine) were
the only materials left in the pack; Pastel's gem fragments now count as an
eighth of a gem, and Create: Wizardry's arcane sheet, arcane block and mithril
nugget feed the metals they are made of, through extensions in its own pack so
they cost nothing to anyone without it.

Four modules of our own, in packs gated on the addon whose slots they use:

- A khopesh blade for any sword blade slot - axe damage, a point of knockback,
  an axe's mining level, fast, and short-reached and fragile to pay for it.
  Nothing in the ecosystem ships one, so it is drawn here.
- Socketed pommels. Arsenal's own socket pommel takes a small gem, and no
  module anywhere in Arsenal, Armory, Archery or MIAPI offers a gem_melee_large
  slot, so the large gemstone had nowhere to go. Now it does.
- A sealed helmet and a life support pack. Cosmonautics suffocates you in space
  through LivingBreatheEvent and exempts only items that *are* a Create diving
  helmet, which a modular helmet cannot be, so VacuumSeal.java answers the same
  event last. Half a seal each: it takes the suit, not the hat.

Arcane alloy is what it is called in game - Create: Wizardry renames the ingot -
and cutting spell cooldowns is now the reason to build out of it: 10% held per
module, less on armour, on Iron's Spells' cooldown * (2 - value), so a weapon
made of it beats the mod's best staff and a full kit still stays inside the
formula.

Two bugs found on the way: the Ice and Fire amethyst extension named an item
that does not exist (the mod spells it amythest_gem) in a shape MIAPI's codec
does not read, so it had never done anything - extensions are item-checked like
materials now. And the generator handed a namespace to whichever jar sorted
first, which is an addon as often as the mod that owns it; it goes to the jar
with the most of it now. A mod whose jar is missing is skipped with its files
left alone rather than failing the run, and only material folders are cleared,
since the module packs are hand-written.

Module art is placeholder-grade and meant to be repainted: it lives in
textures/items and textures/equipment, with blank templates and a guide sheet
giving the palette stops and every region a model samples.

+**Breathing in a vacuum.** The same trick, for the space set - see below.
+
+## Modules
+
+Three of the packs hold modules rather than materials. They are hand-written
+rather than generated, and gated on the Truly Modular addon whose slots they use.
+
+**Khopesh blade** (`packs/arsenal`) fits any `sword_blade` slot, so it is an
+option wherever the plain sword blade is. It is the chopping sword it looks
+like: axe damage off hardness *and* density, a full point of knockback, an axe's
+mining level so it fells trees and strips logs, and a fast swing. The cost is
+everything a hook gives up - shorter reach than a sword, no sweep, and a quarter
+less durability than the blade it replaces.
+
+There was no khopesh to borrow. Nothing in the Truly Modular ecosystem ships
+one, and the khopesh art that exists elsewhere is either another mod's item or a
+retexture of a vanilla sword - neither is a MIAPI module and neither is ours to
+ship, so the blade is drawn here.
+
+**Socketed pommels** (`packs/arsenal`) give the bigger gems somewhere to sit.
+Arsenal does ship a socket pommel, but it takes a small gem, and a sweep of
+Arsenal, Armory, Archery and MIAPI turns up no module anywhere that offers a
+`gem_melee_large` slot - the large gemstone is defined and then has nowhere to
+go. So there are two here: a medium socket, and a great socket for the large
+gem. Each is a heavier counterweight than the last, paid for in swing speed.
+
+**The space set** (`packs/armory`) is Create: Cosmonautics' answer to vacuum,
+rebuilt as modules. Cosmonautics suffocates you above the atmosphere by
+answering NeoForge's `LivingBreatheEvent` with "no", and exempts its own space
+helmet through Create's diving code, which asks whether the worn helmet *is a*
+`DivingHelmetItem`. A modular helmet cannot be one, so the exemption is
+unreachable and the set brings its own: `VacuumSeal.java` registers a
+`cmmodular:vacuum_seal` attribute and answers the same event last.
+
+It takes two modules to reach the seal. The sealed helmet grants 0.5 and the
+life support pack on the chest grants 0.5, and only at 1 does the wearer
+breathe - so it is a suit, not a hat, which is the same trade Cosmonautics makes
+by pairing its helmet with a jetpack. Both come in a socketed version that
+trades 5% armour for a medium gem slot, exactly as Armory's own socket pieces
+do, and each socketed version has its own model and texture with the setting
+drawn in, rather than wearing the plain piece's art.
+
+All of the art here is placeholder-grade and meant to be repainted - see
+Textures below.

   material properties they accept and list only `default` plus their own gem
   tags. Anything filed under `armor`/`handheld` silently never applies to a
   socketed gem. The attribute's own slot is what decides where it counts.
+- Arcane alloy shortens Iron's Spells cooldowns, and that is the point of it:
+  0.10 held, 0.05 on a helmet, 0.03 on the lower armour, filed under `default`
+  so a suit plated in it counts as well as a staff made of it. Iron's Spells
+  reads the attribute as a factor on a base of 1 and spends it as
+  `cooldown * (2 - value)`, so the operation is `*` - a flat `+` would be added
+  to a base of zero and do nothing - and 0.10 means 10% off the wait. It stacks
+  per module, so a weapon built entirely of arcane alloy is around 40%, against
+  25% for Iron's Spells' own best staff; a full set adds roughly another 45%,
+  which keeps even an all-arcane player under the 100% where the formula
+  bottoms out. The material
+  is called Arcane Alloy rather than Arcane Steel because Create: Wizardry
+  renames the ingot that way, and Create: Wizardry's arcane sheet and block are
+  the same metal - they arrive as a material extension in that mod's own pack,
+  since naming them directly would break the material for anyone without it.
+- Platinum comes from Create Propulsion: Simulated, the only platinum in the
+  pack. It is soft for its density, so it swings slowly and hits like steel; it
+  is worth mining for gold-grade enchantability that does not fall apart, and it
+  is heat proof because platinum melts at 1768C.
+- Aviation alloy is AeroEngine's, iron superheated with netherite powder. A
+  turbine superalloy: light and heat proof like titanium, harder, worse to
+  enchant. It sits between titanium and titanium alloy, which is where its
+  recipe sits too.
+- Extensions are material files with a different shape - `parent` naming the
+  material to edit and `data` merged onto a copy of it, the same form MIAPI's
+  stained glass uses to vary plain glass. The merge replaces a field rather than
+  appending to it, so an extension that adds an ingredient repeats the ones it
+  keeps; `_extend_with_extra_forms` builds those lists from the material itself.
+- Ice and Fire's amethyst gem is spelled `amythest_gem` in Ice and Fire. The
+  extension named the correct spelling, which is an item that does not exist, so
+  it did nothing. Extensions are item-checked like materials now.
+- Pastel's paltaeria and stratine gems break into eight fragments on an anvil,
+  so a fragment counts as an eighth of a gem, the way a nugget counts as a ninth
+  of an ingot.
