be6a8053b6 feat(scope): add async resolve tracing and internal documentation
- Added detailed async resolve tracing through CherrypickObserver in _sharedAsyncResolveCurrentScope: logs for request, cache HIT/MISS, start/success/error, and circular dependency detection.
- Improved and extended documentation (docstrings) for private cache fields, paramsToKey, cacheKey, _sharedAsyncResolveCurrentScope, and other internal Scope methods.
- Fixed an unused stack trace variable to resolve linter warning.
- Improved code readability and diagnostic coverage.
- Updated related tests: cycle_detector_test and scope_test for better clarity.
- Updated pubspec.lock as a side effect of technical changes.

BREAKING CHANGE:
Additional diagnostic log messages are now produced during async DI resolution. If you rely on log output parsing or trace handling, adjust your tools for new async trace events.

## Analysis
- **get_it** is the absolute leader in all scenarios, especially under deep/nested chains and async.
- **cherrypick** is highly competitive and much faster than riverpod on any complex graph.
- **riverpod** is only suitable for small/simple DI graphs due to major slowdowns with depth, async, or override.
- **get_it** remains the clear leader for both speed and memory usage (lowest latency across most scenarios; excellent memory efficiency even on deep chains).
- **kiwi** shows the lowest memory footprint in chainSingleton, but is unavailable for async chains.
- **yx_scope** demonstrates highly stable performance for both sync and async chains, often at the cost of higher memory usage, especially in the register/override scenarios.
- **cherrypick** comfortably beats riverpod, but is outperformed by get_it/kiwi/yx_scope, especially on async and heavy nested chains. It uses a bit less memory than yx_scope and kiwi, but can spike in memory/latency for override.
- **riverpod** is unsuitable for deep or async chains—latency and memory usage grow rapidly.
- **Peak memory (RSS):** usually around 320340 MB for all DI; riverpod/kiwi occasionally drops below 300MB. named/factory scenarios use much less.
- **Stability:** yx_scope and get_it have the lowest latency spikes; cherrypick can show peaks on override/async; riverpod is least stable on async (stddev/mean much worse).
### Recommendations
- Use **get_it** for performance-critical and deeply nested graphs.
- Use **cherrypick** for scalable/testable apps if a small speed loss is acceptable.
- Use **riverpod** only if you rely on Flutter integration and your DI chains are simple.
- **get_it** (and often **kiwi**, if you don't need async): best for ultra-fast deep graphs and minimum peak memory.
- **yx_scope**: best blend of performance and async stability; perfect for production mixed DI.
- **cherrypick**: great for modular/testable architectures, unless absolute peak is needed; lower memory than yx_scope in some scenarios.
- **riverpod**: only for shallow DI or UI wiring in Flutter.

## Краткий анализ и рекомендации
- **get_it** всегда лидер, особенно на глубине/асинхронных графах.
- **cherrypick** заметно быстрее riverpod на сложных сценариях, опережая его в разы.
- **riverpod** подходит только для простых/небольших графов — при росте глубины или async/override резко проигрывает по скорости.
- **get_it** — абсолютный лидер по скорости и памяти на всех графах (минимальная задержка, небольшой peak RSS в любых цепочках).
- **kiwi** — минимальное потребление памяти в chainSingleton/Factory, но не для асинхронности.
- **yx_scope** — очень ровная производительность даже на сложных async/sync-цепях, иногда с пиком в памяти на override/register, но задержки всегда минимальны.
- **cherrypick** — стабильнее riverpod, но ощутимо уступает top-3 по латентности на длинных/async-графах; по памяти лучше yx_scope для override/named.
- **riverpod** — непригоден для глубоких/async-графов: память и время растут очень сильно.
- **Пиковое потребление памяти**: большинство DI держится в районе 320340 Мб (большие цепи), на мелких named/factory — крайне мало.
- **Стабильность**: yx_scope и get_it показывают наименьшие скачки времени; у cherrypick иногда всплески на override/async, у riverpod — на async графе stddev почти равен mean!
### Рекомендации
- Используйте **get_it** для критичных к скорости приложений/сложных графов зависимостей.
- Выбирайте **cherrypick** для масштабируемых, тестируемых архитектур, если микросекундная разница не критична.
- **riverpod** уместен только для реактивного UI или простых графов DI.
- Используйте **get_it** (или **kiwi**, если не нужен async) для максимальной производительности и минимального пикового использования памяти.
- **yx_scope** — идеально для production-графов с миксом sync/async.
- **cherrypick** — хорошо для модульных и тестируемых приложений, если не требуется абсолютная “микросекундная” производительность.
- **riverpod** — только если граф плоский или нужно DI только для UI во Flutter.
