1.21.6's copy only differed from 1.21.7's in RenderScopeImpl: item
rendering uses ItemRenderState, which 1.21.7 renamed to
KeyedItemRenderState. That's behind a version comment; 1.21.6 keeps its
older loader_version (0.18.5) in its gradle.properties.
Moving a version over leaves the old mc-<v> project's compiled classes in
the shared build/ folder, so a removed class (1.21.6's dead NameTagMixin)
still got packaged until a clean. VERSION_GUIDE now says to run
:<v>:clean once after moving a version.

Step 5 of #8. versions/1.21.7/src is gone; 1.21.7 builds from src/ as
:1.21.7.
1.21.7's copy differed from 1.21.8's in the player render state: Fabric
API's RenderStateDataKey only exists from 1.21.8 (fabric-rendering-v1
12.6.0), so 1.21.7 had no updateRenderState hook, no SaturnRenderState,
and looked players up by name for the cloak and hat. That stays the case:
- The cloak and hat use getData on >=1.21.8 and SaturnPlayer.get(name)
before that.
- PlayerEntityRendererMixin's updateRenderState exists only on >=1.21.8,
as flat ranges (>=1.21.9, else if >=1.21.8) calling a shared
saturn$applyPlayer helper, instead of nested version blocks.
- SaturnRenderState's key only exists on >=1.21.8; the class is empty
before.
- TODO: 1.21.6 and 1.21.7 still don't show the role icon in names.
1.21.7's NameTagMixin isn't carried over: it wasn't registered in any
mixin config, so it never ran.
The 1.21.7 jar differs from the old one only as 1.21.8's did in step 4
(entityAlpha and drawGroup helpers, getIconId, and the cloak getting its
buffer at the draw call), plus the empty SaturnRenderState and the
missing dead NameTagMixin. 1.21.8-1.21.11 only differ in
PlayerEntityRendererMixin (the helper).

Step 4 of #8, the first version before the 1.21.9 render queue.
versions/1.21.8/src is gone; 1.21.8 builds from src/ as :1.21.8.
API differences behind version comments (<1.21.9 / >=1.21.9):
- Player cosmetics: FeatureRenderer.render takes a VertexConsumerProvider
instead of the render queue. The cloak, hat and OBJ renderers name the
render target "output" in both, so only the parameter type and the final
draw call differ; the OBJ face loop moved into drawGroup.
- PlayerEntityRenderer.updateRenderState's entity type, the cape texture
accessor, GameProfile getName()/getId() vs name()/id(), fonts in
TextMixin, EntityRenderDispatcher vs EntityRenderManager, Screen input
events (Click/KeyInput), and KeyBinding categories and isKeyPressed.
Features 1.21.9+ lacks stay on 1.21.8, with a TODO for 1.21.9+:
- NametagsMixin moves into src/. It hooks renderLabelIfPresent with a
VertexConsumerProvider, which 1.21.9 changed, so on 1.21.9+ its body is
empty; it stays registered, so features.mixins.json is the same for
every version.
- The splash screen's loading-bar border, and the real drag deltas in
SaturnScreenFabric.mouseDragged.
- Status effect icons keep 1.21.8's GUI atlas sprite; 1.21.9+ draws the
texture instead (getIconId), as before.
Behaviour changes on 1.21.8: the cloak and hat read the Saturn player from
the render state (set by PlayerEntityRendererMixin, by UUID) instead of
looking it up by name, and the display-name null check applies.

Step 3 of #8. 1.21.9's copy was identical to the old 1.21.10 one, so the
existing version comments already cover it and no code changes: 1.21.9 is
added to stonecutterVersions and versions/1.21.9/src is removed.
Like 1.21.10 in step 2, 1.21.9 now renders hats (1.21.11's render-queue
implementation) and gets the display-name null check. The jar has the same
entries, fabric.mod.json and mixin configs as before; only those classes
and ShaderUtils's entityAlpha helper differ in bytecode.

Step 2 of #8. versions/1.21.10/src is gone; 1.21.10 builds from src/ as
:1.21.10, with versions/1.21.10 keeping only gradle.properties and run/.
API differences go behind version comments: render layers (ShaderUtils),
Camera.update's World vs BlockView (CameraMixin), the text and textured-quad
render states (RenderScopeImpl), Screen.init (SplashOverlayMixin) and
jspecify's @NonNull (SaturnRenderState).
Features 1.21.11 leaves out stay on 1.21.10, with a TODO for 1.21.11:
WorldFeatureImpl.getWorldAge, SaturnScreenFabric.resize and
EntityDrawerImpl clearing the hitbox.
Hats now render on 1.21.10: its HatFeatureRenderer overrode the
render-queue method with an empty body, and the working code sat in an old
VertexConsumerProvider method nothing called. 1.21.10 now uses 1.21.11's
render-queue implementation (HatFeatureRenderer, ObjModel, ObjRenderer),
and also gets 1.21.11's null check on the player's display name.
The 1.21.10 jar has the same entries, fabric.mod.json and mixin configs as
before; only those four classes and ShaderUtils (a helper method for
entityAlpha) have different bytecode. The 1.21.11 jar only differs in
ShaderUtils.

- settings.gradle, stonecutter.gradle and the root build.gradle become
.kts. Loom's version for the Stonecutter versions moves to the root
gradle.properties (loom_version), read by pluginManagement, since the
Kotlin plugins block can't read properties. The old mc-<v> projects keep
their Groovy scripts until they're folded in.
- buildAll ran all eight remapJar tasks at once. Each loads a Minecraft
classpath and remaps a ~50 MB jar, which doesn't fit in the 3 GB daemon
heap: a cold build stalled in garbage collection for 40+ minutes, and
earlier runs failed. A shared build service now lets two remaps run
together; a cold buildAll takes about 2 minutes.
- port.sh and VERSION_GUIDE follow the .kts file names.
The 1.21.11 jar is the same as with the Groovy scripts.
