Prepare v0.6.1 release

[fabian-barney]

Summary

• prepare the v0.6.1 patch release across Maven, Gradle, and consumer-facing docs
• add the 0.6.1 changelog entry for the fixes and maintenance merged since v0.6.0
• create the GitHub Release as a draft before public artifact publication, then promote it after Maven Central and Gradle Plugin Portal publication succeeds

Review focus

• .github/workflows/release.yml: draft creation happens before public publish steps, and final release promotion happens last
• version alignment across Maven POMs, gradle-plugin/build.gradle.kts, README examples, and changelog

Validation

• C:\Program Files\Git\bin\bash.exe ./.github/scripts/verify-version-alignment.sh --expected-version 0.6.1
• git diff --check
• git grep -n -F "v0.6.0" -- .
• git grep -n -F "0.6.0" -- pom.xml core/pom.xml cli/pom.xml gradle-plugin/pom.xml maven-plugin/pom.xml gradle-plugin/build.gradle.kts README.md .github/workflows/release.yml

Residual risk

The actual registry publication still depends on the tag-triggered Release workflow and configured repository secrets.

Closes #193
