fix: detect visit() when wrapped in another function call

[pINKmUNster]

Summary

BrowserTestIdentifier::usesFunction() requires the token immediately preceding visit( (or \visit() to be whitespace to classify a test as a browser test:

return $tokens[$i - 1][0] === T_WHITESPACE;

This misses the common pattern of wrapping visit() in another function call, e.g.:

it('opens the dialog', function () {
    someHelper(visit('/'))->click('Add new')->assertSee('New item');
});

Here the token right before visit is (, not whitespace, so isBrowserTest() returns false. The test is then never registered as a browser test, Playwright never starts, and visit() still executes — failing instantly with a WebSocket-not-connected error instead of running as intended.

We hit this in production with a project-wide helper (acknowledgeEnvironment(visit(...)) — clicks through a "testing environment" interstitial before proceeding) used across ~50 test files, all silently never running as real browser tests.

Fix

Also accept ( as a valid token preceding visit:

return $tokens[$i - 1][0] === T_WHITESPACE || $tokens[$i - 1] === '(';

Covers both the plain and fully-qualified (\visit() cases, since the fully-qualified name token check already runs before this line.

Test plan

• Added two regression cases to tests/Unit/Support/BrowserTestIdentifierTest.php: visit() and \visit() wrapped in another function call.
• Verified via a standalone reflection-based script (existing test file's own test closures contain literal visit( tokens, which trips the plugin's own detector and requires a real Playwright install to execute through pest) that all existing cases (plain visit(), \visit(), Livewire::visit(), method-call $page->visit(), string literal, wrapped in another call) resolve correctly with this change — no regressions.
