Add event sourcing pattern review document - #1

Summary

Adds a standalone review document (event-sourcing-review.md) at the repo root analyzing the current state of event sourcing coverage in this repository. The review (written in Turkish) examines the event-driven-architecture, cqrs, event-aggregator, event-queue, and event-asynchronous modules, scoring them against true Event Sourcing principles and proposing a reference architecture for a proper event-sourcing module.

No source code is changed — this is a documentation-only addition.

Review & Testing Checklist for Human

• Verify placement: The file is added at the repo root. Confirm this is the desired location (vs. a docs/ folder or within a specific module).
• Language appropriateness: The document is entirely in Turkish. If this repo should remain English-only, it may need translation.
• Content accuracy: Spot-check a few of the technical claims (e.g., "Event store yok", "HashMap thread-safe degil", CQRS commandes typo) against the actual source to confirm they are correct.
• Typo on final line: "orneginigosteriyor" should be "ornegini gosteriyor" (missing space).

Notes

• This is a pure documentation addition with zero runtime impact.
• The review proposes a reference architecture for a future event-sourcing module but does not implement it.
