Update to Minecraft 26.3

[rubensworks]

Updates all three loaders to Minecraft 26.3, alongside CyclopsMC/CyclopsCore#243. ./gradlew build and ./gradlew runGameTestServer both pass locally — 13 game tests green on Fabric, NeoForge and Forge — and the block was checked in a running 26.3 client.

Tooling

Same set as CyclopsCore:

• Gradle wrapper 9.5.0 → 9.7.1. Fabric Loom 1.18 requires it, and Loom also requires the build JVM itself to be Java 25 (CI already provisions Java 25).
• Fabric Loom 1.17-SNAPSHOT → 1.18.2, NeoForge ModDev 2.0.141 → 2.0.147.
• NeoForge 26.3.0.7-beta, Forge 26.3-66.0.2, Fabric API 0.161.0+26.3, Fabric Loader 0.19.5, NeoForm 26.3-1, Forge Config API Port 26.3.0.

Code

Only two vanilla changes touch this mod, and each hits all three loaders:

• The block type MapCodec registry and Block#codec were removed entirely. The CODEC field and the codec() override are dropped from BlockFlopperFabric, BlockFlopperForge and BlockFlopperNeoForge, along with the imports that became unused.
• PushReaction.DESTROY was renamed to POPPED, in each BlockEntityFlopper*'s piston-push check.

Verified in a 26.3 client

Dropping Block#codec touches registration, so beyond the game tests the block was exercised in a real client with clientdevbridge:

• flopper:flopper registers as both a block and an item.
• Placed, it keeps its blockstate properties: Block{flopper:flopper}[enabled=true,facing=down].
• Its block entity serializes: {components:{},tank:{acceptedFluid:"minecraft:empty",capacity:5000,stacks:[{}]},transferCooldown:-1}.
• With a water source above it, the tank filled to {amount:1000,id:"minecraft:water"} — so fluid pulling still works end to end.
• The block model and the item model both render.

Also note: .gitignore gained an entry for .clientdevbridge/ session state, which the tooling appends on first use.

Both Build checks fail, and it is the blocker described at the top of this PR rather than anything in the diff. Gradle stops at dependency resolution after 50s, before compiling anything:

Could not find org.cyclops.cyclopscore:cyclopscore-26.3-fabric:1.30.0-1038
Required by:
    project ':loader-fabric'

The artifact id embeds the Minecraft version, so bumping minecraft_version to 26.3 moved the coordinate to cyclopscore-26.3-*, and no CyclopsCore 26.3 build is published yet.

There is no fix to port into this PR: what is missing is a published artifact, not a code change. It clears once CyclopsMC/CyclopsCore#243 is merged and its CI publishes, at which point cyclopscore_version in gradle.properties needs bumping from 1.30.0-1038 to that build. I have left a TODO on the property.

Not re-running the checks: a missing artifact is deterministic, so a re-run would fail identically.

Locally this builds and passes — ./gradlew build plus 13 green game tests on all three loaders — against a publishToMavenLocal CyclopsCore through cyclopscore_version_local=1.30.0-DEV in secrets.properties.
