Companion to the compact preflight in #31 — the JSON format was the structured alternative to the verbose text summary. With the new compact text already on screen, no consumer was using the JSON shape, and the abstract `BottlePlan.to_dict` was the biggest piece of API surface no one is implementing against. Removed: - `--format` CLI flag from `start` and `resume`. - `output_format` kwarg from `_launch_bottle`. - `BottlePlan.to_dict` abstract method. - `DockerBottlePlan.to_dict` (60-line dict builder). - The `_PlanView` dataclass — `print` was the only remaining caller, so the env-name computation is inlined. - `tests/integration/test_dry_run_plan.py` (JSON-shape integration test). - `tests/unit/test_cli_start_format.py` (flag-conflict unit). Plan-introspection is still possible by reading the `DockerBottlePlan` dataclass directly — fields like `image`, `container_name`, `stage_dir`, `use_runsc` are all there. Tooling that needs a stable wire shape can JSON-serialize the dataclass themselves. 411 unit + integration tests pass. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
