* Chore: Upgrade PHPUnit to 12, modernize tests, refresh Rector sets

- Bump phpunit/phpunit ^9.5 -> ^12.0, phpstan/phpstan ^2.0 -> ^2.1, rector/rector ^2.0 -> ^2.4.
- Migrate phpunit.xml to the PHPUnit 12 schema; exclude the BaseTest trait and
  the misnamed UtopiaFPMRequestTest mock helper from the unit suite.
- Add PHPUnit 10/11/12, code-quality, and annotations-to-attributes sets to
  rector.php; drop three skip entries rector reported as unregistered; skip
  AssertEmptyNullableObjectToAssertInstanceofRector since it weakens assertNull.
- Apply rector: declare(strict_types=1) in tests, final test classes, generator
  data provider, and assertEquals -> assertSame where types are inferable.
- Manual cleanup: assertEquals(null|true|false, x) -> specific methods; fix
  RequestTest::testCanRemoveHeaders which relied on null == '' loose equality
  (getHeader returns string); replace closure-vs-closure assertEquals in
  RouteTest::testCanSetAndGetAction with assertInstanceOf(Closure::class, ...).

* Chore: Bump swoole test image to appwrite/base:1.2.0 (PHP 8.5)

The CI e2e-swoole job failed because appwrite/base:0.5.0 ships PHP 8.2.6,
but PHPUnit 12 requires PHP >= 8.3. Bumping to 1.2.0 (PHP 8.5.4, swoole
included) matches the library's >=8.3 floor and the host test runtime.

Drop the now-redundant curl_close() call in tests/e2e/Client.php — PHP 8.5
deprecates it (the handle is released on last reference since 8.0 anyway).

* Chore: Declare coverage source in phpunit.xml

PHPUnit 12 requires a <source> section for coverage to run; without it the
runner emits "No filter is configured, code coverage will not be processed"
and CI's --coverage-* flags exit non-zero. Point coverage at ./src.

* Chore: Add PHPUnit schema reference, tighten Route/Response assertions

- phpunit.xml: add xmlns:xsi and xsi:noNamespaceSchemaLocation pointing at
  vendor/phpunit/phpunit/phpunit.xsd so PHPUnit 12 (and IDE tooling) get
  XML schema validation.
- HttpTest: swap reversed assertEquals(actual, expected) pairs in
  testCanSetRoute, testCanMatchRoute, and testCanMatchFreshRoute to the
  expected-first convention, and promote them to assertSame — setRoute
  and match return the exact Route instance, so identity is the precise
  check and the diff on failure reads correctly.
- ResponseTest: promote fluent-interface assertions on addHeader /
  addCookie to assertSame for the same reason.
