Builds a modern, testable API for the Prologix GPIB-ETHERNET controller (GPIB-USB structurally supported but untested, no hardware available): Transport abstraction (Ethernet now, serial later), GpibController for the full "++" command set, a clean-room netfinder discovery client that fixes a real chr()/struct-format bug present in vendortools/nfutil.py, and a CLI (discover/config/info/terminal). vendortools/, pty-gpib-emulator/, sampledata.txt and the manual PDF are kept untouched as reference material. Depends on the sibling bits package (editable, not yet pinned -- see its own commit) for MAC formatting and IEEE-488.2 status-byte bit access. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
