Detailed Description

Implements the OP_RUST_GET_SP opcode (conditional build).

Delegates to a Rust helper to read the VM's current stack pointer (sp). When Rust support is disabled, this raises a runtime error and pushes -1 to signal unavailability.

OP_RUST_GET_SP: () -> int | Nil

Behavior (FUN_WITH_RUST=ON):

• Does not pop any values.
• Invokes fun_op_rget_sp(vm). The Rust helper may push the result or otherwise communicate it. The C side does not directly push here.

Behavior (FUN_WITH_RUST=OFF):

• Raises a runtime error indicating missing Rust support.
• Pushes integer -1 as a sentinel value.
