docs: streamline README - #142

📝 WalkthroughWalkthroughREADME.md was replaced with a concise overview of Kevlar. It now covers installation, shield usage, failure handling, composition, HTTP and dependency-injection integration, package offerings, and documentation links. ChangesREADME Documentation
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🔵 Low · up to The README currently suggests that timeouts and abandoned attempts always stop underlying work, although cancellation is only requested and may be ignored by delegates or downstream APIs. Clarifying this before or with merge avoids misleading users about retry and hedge behavior. Poem

In `@README.md`:
- Around line 32-34: Update the README execution-order explanation to clarify
that the cancellation token requests cancellation rather than forcibly stopping
work; delegates and downstream APIs must observe the token, otherwise
synchronous or token-ignoring asynchronous work may continue after the shield
returns and overlap retries or hedges.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Document cooperative cancellation.
This wording states that timeouts and abandoned attempts stop the underlying work. A synchronous delegate or an asynchronous delegate that ignores ct can continue after the shield returns. Retries and hedges can then overlap that work.
Clarify that the token requests cancellation and that the delegate and downstream APIs must observe it.
Proposed wording
- The cancellation token passed
- to your delegate is important—it is how timeouts and abandoned attempts stop the underlying work.
+ The cancellation token passed
+ to your delegate lets timeouts and abandoned attempts request cancellation. Your delegate and
+ downstream APIs must observe `ct`; otherwise, the underlying work can continue after the shield returns.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
