Treat the status line as Cloudflare's primary purge signal

[Meldiron]

What

Aligns the Cloudflare adapter's success check with the Fastly adapter: an HTTP 2xx is acceptance, and the response envelope's explicit verdict is honored when present — a success: false inside a 2xx still fails the purge, but a 2xx without a parseable envelope no longer does.

Why

Cloudflare's v4 API reports failures with non-2xx status codes; the envelope duplicates that verdict. Requiring the envelope to be present meant a 2xx whose body a gateway rewrote, a proxy dropped, or a test double never sent was reported as a failed purge that had actually been accepted — the caller then retries or alerts on nothing. Keeping the explicit-success: false override preserves the one real protection the body check provided.

Tests

• testAcceptsAPurgeWithoutTheEnvelope — 200 with an empty body is acceptance
• testRejectsAPurgeTheBodyReportsAsFailed — unchanged: explicit success: false in a 2xx still rejected
• testRejectsAPurgeTheStatusReportsAsFailed — a failing status is not softened by the envelope

Suite: 52 tests, 115 assertions, green. Pint and PHPStan pass.

Greptile Summary

This PR makes Cloudflare purge handling treat an HTTP 2xx status as acceptance unless a parsed response envelope explicitly reports failure.

• Preserves rejection of non-2xx responses and success: false envelopes.
• Accepts successful responses with empty or unparseable bodies.
• Adds focused tests for missing envelopes and status-level failures.

Confidence Score: 5/5

The PR appears safe to merge with no blocking or independently actionable non-blocking issues identified.

The changed logic rejects every non-2xx response and any parsed envelope whose explicit success verdict is not true, while intentionally accepting 2xx responses without a usable envelope as described and tested.
