Switch the root build scripts to Kotlin and limit parallel remaps

- 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.

-## ✨ About
+## About
 
 Saturn Client is a free, open-source Minecraft client designed to enhance the gameplay experience while staying lightweight and customizable.
 Our goal is to build a clean, optimized client that the community can contribute to and improve together.
 
-Saturn is currently trying to support multiple versions of minecraft, so please report any issues you are experiencing.
+Saturn runs on Fabric and supports **Minecraft 1.21.4 to 1.21.11**, with one build per version. If something doesn't work on your version, please open an issue.

+## Features

----
+## Installation
 
-## 🤝 Contributing
+1. Install [Fabric Loader](https://fabricmc.net/use/) and [Fabric API](https://modrinth.com/mod/fabric-api) for your Minecraft version.
+2. Download the Saturn Client jar for the same version from [Modrinth](https://modrinth.com/mod/saturnclient) or the [releases page](https://git.selimaj.dev/saturnclientmc/saturnclient/releases).
+3. Put it in your `mods` folder.
+
+### Network use
+
+For cosmetics, Saturn Client connects to the Saturn server (`saturn-server.selimaj.dev`). You're signed in the same way as on an online-mode Minecraft server: your client proves who you are to Mojang's session server, and the Saturn server asks Mojang to confirm it. **Your Minecraft access token is only ever sent to Mojang, never to the Saturn server.**
+
+## Building from source
+
+The version-independent code lives in the `common` submodule, so clone with submodules:
+
+```sh
+git clone --recurse-submodules https://git.selimaj.dev/saturnclientmc/saturnclient.git
+cd saturnclient
+
+./gradlew buildAll                    # every version → build/allJars/
+./gradlew :1.21.11:build              # a single version (versions not on Stonecutter yet: :mc-1.21.10)
+./gradlew :1.21.11:runClient          # launch a development client
+```
+
+Building needs Java 21.

 # Version guide
 
-This guide will help you to add or edit minecraft versions.
+How Saturn Client supports several Minecraft versions, and how to change or add one.
+
+## Layout
+
+Saturn is moving from one full copy of the version-specific code per Minecraft version to a single copy built with [Stonecutter](https://stonecutter.kikugie.dev/) (issue #8). During the move there are two kinds of version:
+
+- `common/`: all version-independent code (mods, UI, cosmetics, the server client). It has no Minecraft dependency and reaches the game only through the interfaces in `org.saturnclient.common`.
+- `src/`: the version-specific code (providers, refs, mixins and the three mixin configs) for the versions built by Stonecutter, currently **1.21.11**. It's one copy: where Minecraft's API differs between them, the code goes behind version comments (see below). Each of these versions is the Gradle project `:<mc>`, and `versions/<mc>/` holds only its `gradle.properties` (Minecraft, Yarn, Fabric Loader and Fabric API versions), `build/` and `run/`.
+- `versions/<mc>/src/`: the versions not moved yet (1.21.4 to 1.21.10), each a full copy, as the Gradle project `:mc-<mc>` with its own `build.gradle`.
+
+`settings.gradle.kts` lists the Stonecutter versions in `stonecutterVersions` and includes every other folder under `versions/` as `:mc-<mc>`. The root `build.gradle.kts` builds each Stonecutter version, and `stonecutter.gradle.kts` configures the root project (shared repositories, the `common` wiring and `buildAll`). Loom's version for the Stonecutter versions is `loom_version` in the root `gradle.properties`.
+
+## Version-specific code with Stonecutter
+
+The code in `src/` is always plain Java for the **active** version (1.21.11, set in `stonecutter.gradle.kts`). Code for other versions sits in comments that Stonecutter swaps before building each version:
+
+```java
+//? if >=1.21.9 {
+public void render(MatrixStack matrices, OrderedRenderCommandQueue queue, int light, PlayerEntityRenderState state, float limbAngle, float limbDistance) {
+//?} else
+/*public void render(MatrixStack matrices, VertexConsumerProvider consumers, int light, PlayerEntityRenderState state, float limbAngle, float limbDistance) {*/
+```
+
+- `./gradlew "Set active project to <mc>"` (or the Stonecutter IntelliJ plugin) rewrites `src/` so that version's code is the uncommented one, for editing it in the IDE.
+- `./gradlew "Reset active project"` switches back to 1.21.11. **Run it before committing**, so `src/` is always committed with 1.21.11 active.
+- Each version's processed copy is compiled from `versions/<mc>/build/generated/stonecutter/`, which is also where to look when a non-active version fails to compile.
+
+The `emotes` repository uses the same setup, and its `BentCubeRenderer` and `PlayerModelMixin` are small examples of version comments.
+
+## Porting a change to the other versions
+
+Make the change in one version, usually the newest, then run:
+
+```sh
+scripts/port.sh                        # port uncommitted changes to every other version
+scripts/port.sh --dry-run              # see what would apply cleanly first
+scripts/port.sh --to 1.21.9,1.21.10    # only some versions
+scripts/port.sh --commit <rev>         # port what a commit changed instead
+```
+
+The script applies the diff under one version's source to each other version with `git apply --3way`. The Stonecutter `src/` counts as one version (1.21.11), so changes port between it and the old copies in both directions:
+
+- **applied**: the files matched, and nothing else is needed.
+- **CONFLICTS**: that version's code really differs. The file gets normal conflict markers, with the version's own code in `ours` and the ported change in `theirs`. Adapt the change to that version's API and resolve.
+- **already has this change**: nothing to do, which is safe to see when re-running.
+
+Only source is ported. `build.gradle` and `gradle.properties` are version-specific on purpose. Then build everything:
+
+```sh
+./gradlew compileJava
+```
+
+The **Check** workflow runs the same compile on every pull request, so a version that was missed or mis-ported fails before merging.
+
+## Adding a Minecraft version
+
+Add new versions to Stonecutter rather than copying a folder:
+
+1. Create `versions/<new>/gradle.properties` with `minecraft_version`, `yarn_mappings`, `loader_version` and `fabric_api_version` (copy 1.21.11's and change the values; they're listed at <https://fabricmc.net/develop>). Loom's version is shared, in the root `gradle.properties`.
+2. Add `<new>` to `stonecutterVersions` in `settings.gradle.kts`.
+3. Build it with `./gradlew :<new>:compileJava` and put what Minecraft changed behind version comments. Check the mixin configs in `src/main/resources/*.mixins.json` as well: a mixin whose target changed fails at startup, not at compile time, so launch it with `./gradlew :<new>:runClient`.
+4. The release workflow builds everything through `buildAll`, and "Publish to Modrinth" takes the game version from each jar's name, so neither needs changing.
