…types FormatVersion::V1 emits the pre-0.5.0 JSON shape: ChainReport.chains as flat string arrays, TraceReport.PackageEntry without edge_kinds or classification. V2 is the current shape. All reports include a format_version field in JSON output. Existing to_json() delegates to to_json_versioned(V2) for backward compat with REPL callers.
Consumers pass --format-version 1 or 2 to pin the JSON schema. When --json is used without --format-version, stderr warns and defaults to 2. Threaded through all emit call sites in main.rs.
