JetBrains Air adds local model support and Java/Kotlin code intelligence.

The update expands the agent roster, adds local model execution, and deepens JVM-language intelligence. Local models in an agentic IDE matter for regulated shops that can't ship source to a vendor endpoint, the same sovereignty pattern Microsoft pushed with Foundry Local. JVM coverage is also the real gap: most agentic editors are excellent at TypeScript and Python and mediocre at Kotlin and Java.
