[Bug]: Running tests in parallel causes SQLSTATE[HY000] [2006] MySQL server has gone away

What Happened

When I run tests in parallel by using vendor/bin/pest --parallel, it fails most about 75% of the tests with SQLSTATE[HY000] [2006] MySQL server has gone away.

  ────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
   FAILED  Tests\Feature\REDACTED > REDACTED                                        QueryException
  SQLSTATE[HY000] [2006] MySQL server has gone away (Connection: mysql, SQL: drop database if exists `REDACTED`)

How to Reproduce

In a repository with multiple tests that access the database, run vendor/bin/pest --parallel.

Sample Repository

No response

Pest Version

2.34.7

PHP Version

8.3.7 and 8.2.19 through Valet

Operation System

macOS

Notes

Running the tests consecutively has never given me any issues.

I am using mysqld 5.7.44 through Homebrew

I have tried configuring /opt/homebrew/etc/my.cnf by adding the following:

[mysqld]
max_allowed_packet=100M
connect_timeout=600

These are commonly suggested configurations when encountering this specific error.

I have also tried both using a socket connection and connecting to 127.0.0.1 and localhost.

The reason I'm posting this as an issue in this repo is that I think Pest should manage the connection correctly.
