Function is_throw_node

internal/cbm/extract_semantic.c:27–38

Detect whether a node is a throw node for the given spec. Kotlin special case: this grammar models `throw X(...)` as a `jump_expression` (the same node also covers return/break/continue), NOT a `throw_expression`, so the spec's throw_node_types ("throw_expression") never matches. We treat a Kotlin `jump_expression` as a throw only when its first child is the `throw` keyword, which excludes retur

// Kotlin `jump_expression` as a throw only when its first child is the `throw`
