Pull Request Overview

This PR migrates the io.spine.logging.jvm.parameter package (and related visitor/parser logic) from Java to Kotlin, adds @Immutable and @ThreadSafe annotations across the codebase, and standardizes the ordering of arguments in the of() factory methods.

• Replace Java Parameter, SimpleParameter, DateTimeParameter, BraceStyleParameter, and ParameterVisitor with Kotlin equivalents and update tests to use ArgumentVisitor.
• Add @Immutable and @ThreadSafe annotations on many classes for thread-safety documentation.
• Change SimpleParameter.of() signature from (index, formatChar, options) to (formatChar, options, index) and update all call sites and tests accordingly.

• Reordering the factory method parameters is a breaking change for Java callers; consider adding a deprecated overload of(index: Int, formatChar: FormatChar, options: FormatOptions) that delegates to the new method for backward compatibility.

        public fun of(formatChar: FormatChar, options: FormatOptions, index: Int): Parameter {

• [nitpick] Kotlin object declarations are inherently thread-safe, so the @ThreadSafe annotation on the object may be redundant.
