Bug description

PHPantom reports a type mismatch for the valid two-argument strtr() form where the second argument is the replacement-pairs array.

Expected: no diagnostic.
Actual: Argument 2 ($from) expects string, got array{...} with code type_mismatch_argument.

Steps to reproduce

1. Use any supported PHP version.
2. Create a PHP file with:

<?php

$result = strtr('Hello :name', [
    ':name' => 'Alex',
]);

3. Open the file with PHPantom enabled.
4. Check diagnostics on the second argument.

Error output or panic trace

.phpantom.toml

No version-specific settings are required.

Additional context

strtr() has two valid signatures:

strtr(string $string, string $from, string $to): string
strtr(string $string, array $replace_pairs): string

PHPantom appears to validate the call against the three-argument string signature only.
