New idea for remote CC

After reviewing #85 (good work keep it going!) I thought of a different approach to code coverage that might work cleanly as well.

The idea:
1. Before a test starts, connect to C3, this is a "long lived" connection. C3 creates a file temp file with a fixed name and watches it for data, this data is streamed back to the coverage module.
2. During the test each request to the server is profiled and the serialized result (php-codecoverage library supports serialization) is atomically written to the local temp file.
3. After the test ends we disconnect the stream from 1 and this prompts the remote coverage file to be removed

This could simplify things:
- We no longer need to mark each request with a cookie, which needs to be set in the browser module (Selenium, REST, or Php)
- We no longer have edge cases where fetch requests might not send cookies for example
- We cannot support parallel tests since we won't be able to know to which test the coverage belongs

## Streaming coverage
We can stream coverage for each request like this using the PHP report class (copied below since its short)
```php
final class PHP
{
public function process(CodeCoverage $coverage, ?string $target = null): string
{
$coverage->clearCache();

$buffer = "append($unserializedCoverage)`

Optionally we could do some automatic path detection which in most cases should actually be trivial.

Thoughts?

Bắt đầu bằng việc xem xét issue #85 và quy trình coverage từ xa C3 hiện có, bao gồm cách các module trình duyệt Selenium, REST và Php hiện nhận diện các request. Tiếp theo, lần theo đường đi của báo cáo PHP CodeCoverage và quá trình serialization, rồi thống nhất với các maintainer về hành vi của kết nối, streaming, cleanup và kiểm thử song song trước khi triển khai.
