Title: Version placeholder ${version} not expanded in fabric.mod.json

Hi,

When loading the mod on Fabric Loader 0.18.4 (Minecraft 1.21.11), the following warning appears:

Mod free-inventory uses the version ${version}
Could not parse version number component '${version}'

It looks like the version field in fabric.mod.json was not expanded during build, and still contains the placeholder:

"version": "${version}"

Because of this, Fabric Loader cannot parse the mod version using extended SemVer format.

Environment:

• Minecraft 1.21.11
• Fabric Loader 0.18.4
• Java 21

Suggested fix:
Ensure that the version property is properly expanded during the Gradle build, for example:

processResources {
inputs.property "version", project.version
filesMatching("fabric.mod.json") {
expand "version": project.version
}
}

This does not affect functionality, but it produces a warning at startup and prevents proper semantic version handling.

I will submit a PR to address this.

Thanks!
