Fetch Address Lookup Table

Summary

The mplx toolbox lut fetch command reads an Address Lookup Table from the network and prints its authority and contained addresses.

• Resolves the LUT account and lists every address it holds.
• Prints the authority, or None for frozen LUTs.
• Adds deactivation slot and last-extended slot in verbose mode.
• Supports machine-readable JSON output via --json.

Basic Usage
