bbgen 0.1.0

The first public release.

• bbgen places a circuit's parts on one or more breadboards, lays the wires, checks the wiring against the
  nets, and writes a drawing (SVG and PNG) and a build checklist. Give as much or as little of the layout as you
  like: a file can be just parts and nets.
• Parts from KiCad's symbol and footprint libraries (symbol:, footprint:), found with bbgen find; SMD
  parts on DIP adapters.
• --schematic draws the circuit's schematic from the same file, laid out by ELK; --steps and --video show
  the build step by step; --json and --events report it for programs.
• bbgen studio, a desktop app: inspect a build, watch bbgen place and wire it, compare its steps, export its
  files, and follow a build guide at the bench. It rebuilds whenever the circuit file is saved.
• bbgen studio FILE opens a circuit in bbgen studio from a terminal or an agent, and bbgen docs says where
  the circuit file's reference is.
• A Claude Code skill for laying out circuits with an agent.
• A Linux package (x86_64) with a one-line installer.
