Replaces the bpj2ini.py prototype with a packaged tool. The A2F codec is now reimplemented in Python, so neither Boxsim.exe nor a CPU emulator is needed to decode a container; the emulator survives as a development-only oracle that the codec is differentially tested against. Verified: - 134 containers decode byte-identically to Boxsim's own decoder, 270 pre-2.0 files rejected by both implementations (tools/difftest.py --self-test) - Default.BPJ: 22 components, 14 nets, no dangling terminal - 22 of 22 parts resolve to library symbols; one series inferred from a sibling, two DC resistance deviations reported - ERC clean and the netlist KiCad extracts from the generated sheet is an identical partition to the one derived from the Boxsim grid - container build byte-identical to the host build - 32 tests passing, ruff clean Decode time went 69 s -> 14.5 s (binding emulator hooks to trap addresses) -> 1.6 s (pure Python).
