Function disassemble 

pub fn disassemble(ir: u32, pc: u32, syms: Option<&SymbolTable>) -> String

Disassemble one RV32IMA instruction into an objdump-compatible string.

• ir — the 32-bit instruction word.
• pc — virtual address of the instruction, used to compute branch and jump targets relative to PC.
• syms — optional symbol table for resolving target addresses to names.

Returns a string containing the mnemonic and operands, with no leading address and no trailing newline. Example: "jal ra, <vTaskStartScheduler>".
