// Report is the structured change summary produced by a /dream consolidation
// run. It is persisted inside State.LastReport (state.go) and emitted as a
// single line of JSON on the child process stdout (spec §4.2). Every count is a
// deterministic tally the runner fills in after the plan (Go-deterministic) and
// apply (LLM) phases; the zero value is a valid "nothing changed" report.
//
// The JSON tags match spec §3.2 exactly so the parent process (and any
// scripted/headless caller) can decode the stdout contract without a shared Go
// type.
