Add Kotlin language basics

Added language_basics.json for Kotlin 1.5 covering:
- Type system (statically typed)
- Paradigms (OOP, functional, procedural)
- Abstraction level (high-level)
- Execution method (compiled)
- Memory management (automatic/GC)
- Entry points (main function, script files)
- Comments (single-line, multi-line, KDoc, special)
- Library support (standard libs, frameworks)
- Hello World minimal program

Resolves #737
