v0.5: x86-64 disassembly via iced-x86

- state.disasm(n=8), disasm(addr, n=8) -> [{addr, bytes, text, target?, target_sym?}]
- read_mem_pristine() overlays orig bytes through active INT3 breakpoints
- branch/call targets get symbolized when they land in known symbols
- show.disasm / show.bp / show.regs prelude helpers for ergonomic printing
