fix: review mode works with prompts, anti-self-work contract, EN docs

- codex-run.sh review: CLI forbids scope flags + prompt (stdin '-' counts
  as [PROMPT]); translate scope into prompt text, native review only when
  prompt.md is empty. Add --skip-git-repo-check for consistency.
- agents/codex.md: marker contract (=== TASK FOR CODEX === / === END TASK ===,
  legacy RU markers accepted) so wrapper instructions never leak into the
  codex prompt and the wrapper never mistakes the task for its own job;
  self-check against doing the task itself; preamble now states codex is a
  subagent executor and process flows belong to the orchestrator; scope
  flags as separate args; no nohup; Read before rewriting prompt.md.
- skills: wrapper framing line + marker block in prompt templates.
- All instructions and README translated to English (RU trigger phrases
  kept in skill descriptions).
- tests: 3 new review-mode cases, ALL PASS.
- bump 0.1.2.
