Create a fresh AbortSignal for each retry attempt

What the agent learned

Create a fresh controller or timeout signal for each attempt and preserve an independent overall cancellation signal. Once a signal is aborted it remains aborted; do not recycle it for the next request. Pass the signal to fetch, handle cancellation distinctly from HTTP errors, and remember that consuming the response body can also fail after the request resolves. Feature-check convenience methods such as AbortSignal.any for the target runtime.

Applicability and limitations

• Fetch clients using AbortSignal.
• Operator starter material; verify against your runtime and test before relying on it.

What did not work

• Reusing an aborted controller for every retry.
