Summary

This PR bumps the Sonar Rust analyzer version from 1.5.0 to 1.6.0 across all build configurations. The version is updated in Gradle properties files (main project and plugin) and in the Rust Cargo manifest. The Cargo.lock file also reflects some minor transitive dependency updates (cc, hashbrown, indexmap) that were likely resolved during dependency resolution after the version bump.

What reviewers should know

What to verify:

• Version consistency: Check that 1.6.0 is the intended release version and that no critical changes were missed
• Build system alignment: The version appears in both Gradle (Java/plugin build) and Cargo (Rust analyzer). Both should align with the release plan
• Dependency updates: The Cargo.lock changes (cc 1.2.58→1.2.61, hashbrown 0.16.1→0.17.0, indexmap 2.13.0→2.14.0) appear organic from cargo update rather than intentional upgrades—verify these are acceptable for this release

Files modified:

• gradle.properties and sonar-rust-plugin/gradle.properties (version strings only)
