Catching Throwable in non-framework code in PutTaskRequestContent

[elharo]

Affected version: HEAD

} catch (Throwable t) {
    lockedSetTerminal(Content.Chunk.from(t, true));
}

Catches OutOfMemoryError, StackOverflowError, InternalError, etc. These should propagate. Wrapping them as terminal chunks converts fatal JVM errors into regular failure conditions, making them invisible to diagnostics.
