Kotlin Toolchain 0.11: The Next Step for Amper

Amper 0.11.0 has been rebranded as the Kotlin Toolchain and graduated to Alpha status. The release introduces a unified kotlin CLI command for project creation, building, running, testing, and publishing. Key new features include JVM library publishing to Maven repositories and Maven Central (with automatic PGP signing, sources/javadoc JARs, and POM metadata), global CLI installation via SDKMAN!, C interop support via .def files, improved terminal UI with native progress indicators, and module-wide dependency resolution in the IDE. Plugin development gains new APIs including custom checks, custom commands, and a generated section for registering generated files. Several default dependency versions were also updated including Kotlin 2.3.21, Spring Boot 4.0.6, and Ktor 3.4.3. Existing Amper users must replace wrapper scripts and switch to the new IntelliJ IDEA plugin.
