Axel Meyer dea2d8fb88 Wire bake orchestrator and CLI
Connects scan + lock + pack + write into the full pipeline. CLI entry
parses args, dispatches to bake(), prints summary or error. Five
integration tests cover fresh bake, lock-aware ID preservation,
deleted-tile tracking, oversize hard-fail, and bit-identical
determinism across re-bakes.
