Optimize scope timing by using an explicit context manager class instead of @contextmanager decorator. This reduces overhead from generator-based context managers and avoids lambda allocation in no-op decorators.

## Summary Adds test coverage, performance benchmarks, and documentation for the v0.2.0 ergonomics features (decorators, lifecycle hooks, async safety, strict mode). Core implementation was landed in #1. ## Notes - Performance benchmarks were pulled forward from the v0.4.0 roadmap to v0.2.0—they were needed to validate the `_Scope` class optimization and establish baselines. - `NULLSCOPE_STRICT` is documented only in the README env var table for now; design.md addition deferred unless users request clarification. - `uv.lock` is now tracked for reproducible CI.
