fix: recover after a failed Playwright initialize

[tiagoabsantos]

Summary

Fixes pestphp/pest#1938.

Playwright accepts initialize once per WebSocket and sets that flag before the browser launch finishes. If the launch hits the action timeout, $browserTypes stays empty, so the next browser test sends initialize again and every later test fails with Assertion error.

• The one-time launch now uses a 30s timeout, separate from the action timeout.
• A failed initialize closes the socket. The next browser test connects again and can initialize.

Test plan

• tests/Browser/Visit/InitializeRecoveryTest.php forces a second initialize on the same connection, expects Assertion error, then opens a page on a new connection
• Action timeout is unchanged after a successful launch and after the failed initialize
• CI on PHP 8.4 and 8.5
