+글로벌 플래그: `--readonly` (또는 `KEBAB_READONLY=1`) — 모든 write-path 명령 (`ingest` / `ingest-file` / `ingest-stdin` / `reset`) 을 비활성화, exit 1. `--quiet` — 진행 바 / hint 등 human-readable stderr 억제 (exit code / stdout 출력은 그대로). `KEBAB_PROGRESS=plain` — TTY 가 없는 환경에서도 진행 상황을 plain-text 한 줄씩 stderr 로 출력 (spinner 대신).
