Kotlin 2 Kotlin, part1

[9il]

This commit replaces some JVM library calls with cross platform kotlin calls.

It would be great to move towards KMP.

Replaced imports

Java Import	Replacement	Files
java.util.function.Consumer	(T) -> Unit	18
java.util.function.BiConsumer	(A, B) -> Unit	1
java.util.function.Function	(T) -> R	1
java.util.stream.Collectors	Kotlin collection ops (.filter().toList() etc.)	2
java.util.concurrent.CompletableFuture	kotlinx.coroutines.CompletableDeferred	1
java.util.concurrent.Future	kotlinx.coroutines.Deferred	1
java.util.concurrent.ExecutionException	Removed (coroutines throw directly)	1
java.util.concurrent.LinkedBlockingQueue	ArrayDeque + .removeFirstOrNull()	2
java.util.concurrent.ConcurrentLinkedDeque	ArrayDeque	1
java.util.Queue / java.util.Deque	ArrayDeque	3
java.nio.charset.StandardCharsets	Charsets (kotlin.text)	2
java.lang.IllegalArgumentException	IllegalArgumentException (kotlin-stdlib)	1
java.io.Closeable	Closeable (kotlin.io)	1
java.util.ArrayList	ArrayList (kotlin.collections)	1
java.util.Objects	Kotlin !! non-null assertion	1
SAM Consumer { } patterns	Kotlin lambda { } with forEach	6
.stream().filter().collect(Collectors.toList())	.filter().toList()	2

Other changes

• Replaced .accept(x) / .apply(x) calls with direct invocations where Consumer/BiConsumer/Function were removed
• Replaced .stream().filter().findFirst() with .find { } where Stream → Sequence conversion was possible
• Kept java.util.stream.Stream on ProtocolAPIServer and SerialHandler interfaces that Java classes implement

Seems fine, may need to double check that Android doesn't complain about any of these

KMP is the goal. but with the #1798 in progress that aim to that anyway. It feels a bit redundant to do it on the current codebase.

@loucass003 Looks big. Why not incremental changes with AI? It is very accurate and fast. That is the kind of job that AI does better than best engineers.
When the code is already KMP, the design issues can be addressed much easier.

[loucass003]

The structural change is too big to be incremental. I already use Ai to assist in some ways but this is not a magic tool.

Agree, there is a huge tech dept. I thought it could be easier to split language and library change with structural. What maintainers say about your work? I would love it to merged and well tests. I just afraid it could be stalled. I hope it will not

[loucass003]

Main contributors are on board and the slime team too. so it will reach completion. just so you know i am the lead dev of the project. this is happening and not a daydream of some random contributor

Thank you :)
