🔍 What was changed

• New Mutation Tests workflow: PHP 8.4 with Xdebug and ext-msgpack, starts the Go test server, runs Infection over src with --min-msi=90 --min-covered-msi=90 and publishes the 4.x report to the Stryker dashboard on push.
• infection.json.dist writes into runtime/, emits GitHub annotations and the Stryker report; mutation testing badge added to the README.

Review notes

• The Infection phar (0.35.6) cannot run Testo mutants: the bundled testo/bridge-infection writes the unscoped \Infection\StreamWrapper\IncludeInterceptor into the mutant bootstrap, while the phar only has Infected\Infection\..., so every mutant fails with "class not found" and is counted as killed. The workflow installs Infection with Composer inside the job instead; composer.json is unchanged.
• Infection kills the initial test run (exit 143) on the first stderr output; MsgPackMultiRPCTest::testHandlesCloneCorrectly triggers an expected msgpack "Extra bytes" warning, so the job runs with log_errors=Off.
• The STRYKER_DASHBOARD_API_KEY secret is required for the dashboard report and badge.

Checklist

• How was this tested:
  • CI run: 493 mutants, MSI 91%, covered MSI 91%, mutation code coverage 100% (42 escaped, 55 timeouts), about 9 minutes on 3 threads
  • Local run in Linux (PHP 8.4, ext-msgpack, Xdebug) against the test server: MSI 89%
