refactor(skill): плейбук возвращён к оптике тонкого мастера

- Зачем:
  - субагенты должны сохранять внимание мастера и помогать результату, а не обслуживать обязательный конвейер.
- Что:
  - семиступенчатый процесс заменён эвристиками выбора исполнителя, проверяющего и независимого ревьюера.
  - права агентов отделены от канала результата, а полная полезная нагрузка выведена из контекста мастера.
  - добавлены авторитетные договоры промптов, полевые заметки и handoff следующей сессии.
- Проверка:
  - git diff --cached --check.
  - свежий обзор через writing-great-skills, все принятые находки закрыты.

+# Narrow re-check
+
+Re-check only your original findings and the changes immediately adjacent to
+their resolution. Do not perform a full review.
+
+For every original finding report `CLOSED`, `NOT_CLOSED`, `REJECTION_VALID`,
+or `REJECTION_INVALID`, with concise evidence. If this narrow work exposes a
+new adjacent defect, report it in the normal findings format; the scope bound
+limits exploration, not honest reporting.
+
+Return the full re-check through the channel named by the caller. For a file
+channel, write it to the supplied path and return only
+`RECHECK: ALL_CLOSED | ISSUES_REMAIN`, counters, and `REPORT: <absolute path>`.
+For a message channel, return the concise finding statuses once.

+## Result contract
+
+Write the full result through the channel chosen by the caller:
+
+- `STATUS: complete | questions | blocked`
+- `EVIDENCE:` changed files, executed commands, and final counters
+- `DECISIONS:` only questions for the orchestrator or user
+- `FINDINGS:` severity, location, essence, and verification method
+- `NEXT:` one concrete action or `none`
+
+Omit empty sections. Do not include raw output or a reasoning narrative. For a
+file channel, put the full result in the named file and return only status,
+counters, and `REPORT: <absolute path>`. For a message channel, return one
+concise result without a report path.

+## Mandate
+
+- Review and test hypotheses; do not edit source files or persistent
+  environment state.
+- Use the working permissions needed for checks, caches, temporary artifacts,
+  documentation and primary-source research. The caller verifies Git before
+  and after the review.
+- Do not run `git add`, `git commit`, or commands that discard changes.
+- Report only the findings index and verdict through the channel named by the
+  caller.
+
+## Findings index
+
+For each finding:
+
+`SEVERITY(BLOCKER|MAJOR|MINOR|NIT) | file:line or task section | failure scenario | evidence | how to verify`
+
+If there are no findings, list the reviewed scope and every executed check or
+tested hypothesis with its outcome. A bare no-findings assertion is invalid.
+
+Final line: `VERDICT: APPROVED | APPROVED_WITH_MINORS | CHANGES_REQUIRED`

+# Triage blind-review findings
+
+The review indexes below are immutable input. Process every finding and change
+nothing outside their scope. For each finding, either:
+
+- fix it and name the contract or check that proves closure; or
+- reject it with evidence from the contract and a check, never a bare claim.
+
+Do not commit or stage changes. Propose accepted rejections and residual risks
+for the orchestrator to own and record as durable task decisions. The
+orchestrator cannot silently accept risk; authority must come from the user or
+already be explicit in the task.
+
+Write a full resolution report to the path supplied by the caller. Return only
+status, counters, executed checks, and that path in the final message.
