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).
