feat(launch): add bounded external EPF wait

[korolevpavel]

Closes #29

• Adds opt-in launch thin --wait-for-exit for explicit external .epf execution.
• Returns structured PID, execute proof, exit/timeout, and artifact paths; timeout terminates the process group.
• Rejects raw/configured /C, /Execute, /Out aliases in wait mode and redacts composite connection credentials.

Validation: focused CLI wait tests, credential-redaction unit test, cargo test --no-run, fmt and diff checks.

Summary by CodeRabbit

• Новые возможности
  • Добавлен опциональный режим ожидания завершения внешнего EPF при launch thin.
  • Результат запуска теперь содержит PID, код завершения, признак тайм-аута и пути к артефактам.
  • Добавлены параметры --wait-for-exit, --wait-timeout-ms и --stderr-output.
• Улучшения
  • Усилена проверка неподдерживаемых параметров и зарезервированных ключей запуска.
  • Команды test и launch mcp не принимают параметры ожидания внешнего EPF.
  • Конфиденциальные данные в строках подключения маскируются при отображении ошибок.

Warning

Review limit reached

@alkoleft, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 32 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Walkthrough

Добавлен opt-in bounded wait для launch thin с внешним EPF: CLI валидирует параметры, процесс запускается в управляемом режиме, ожидается до таймаута, а результат содержит PID, exit code, timeout и пути артефактов. Обычный асинхронный запуск сохраняется.

Changes

External EPF bounded wait

Layer / File(s)	Summary
CLI и доменные контракты src/cli/args.rs, src/domain/runner.rs, src/domain/launch.rs	Добавлены direct-only wait-флаги, отдельные типы аргументов и структуры ExternalEpfWaitOptions/ExternalEpfWaitResult.
Маппинг и валидация CLI src/cli/execute.rs	Проверяются комбинации wait-параметров и reserved raw keys, формируется external_epf_wait, deadline учитывает bounded wait.
Управляемый запуск процесса src/platform/process.rs	Добавлен ManagedWait, ожидание выхода, перенаправление stderr и очистка process group при таймауте или отмене.
Исполнение external EPF src/use_cases/launch_app.rs	Для ThinClient строится план, запускается EPF и возвращается структурированный результат; timeout возвращает runtime failure с payload.
Проверки и документация tests/cli_*.rs, src/mcp/service.rs, docs/CAPABILITIES.md	Проверены help-ограничения, успешное завершение, таймауты, очистка процессов, reserved keys и MCP-запреты; документация описывает режим.

Estimated code review effort: 4 (Complex) | ~60 minutes

Poem

Я, кролик, жду EPF в тиши,
PID скачет — хвост дрожит.
Таймер тикнул: группа спит,
Exit code всё объяснит.
Артефакты по следам —
Прыг-скок, порядок тут и там!
