#51 - Use the PHP 8.3 to 8.5 functions through the Symfony polyfills, and configure Rector accordingly

[njoubert-cleverage]

Fixes #51

Description

Same change as cleverage/process-bundle#299 (PR cleverage/process-bundle#300), for this bridge.

Changes

• composer.json: require symfony/polyfill-php83, symfony/polyfill-php84 and symfony/polyfill-php85 (^1.33).
• rector.php: withPhpVersion(PhpVersion::PHP_82) (was PHP_85, inconsistent with php >=8.2), withPhpSets() without explicit version (adds Rector's PHP_POLYFILLS set: the rules using a newer function apply when the matching polyfill is required), remove the redundant LevelSetList::UP_TO_PHP_82 and its use.
• Rector rules applied: none, Rector 2.7.0 finds nothing to change with the new configuration.
• Manual replacements: none. The code is small and has no candidate with a strictly identical behaviour:
  • RegisterAdaptersPass::process() and CleverAgeCacheProcessExtension::findServices(): foreach loops with side effects (method calls, file loading), not searches / any / all tests; the latter iterates a Finder (iterator, not an array).
  • AdapterRegistry: array_key_exists() lookups by key, nothing for array_find*().
  • tests/CleverAgeCacheProcessBundleTest::testAdaptersPassIsRegistered(): array_filter() + assertCount(1, ...) asserts that the pass is registered exactly once; array_any() would only check at least once (weaker assertion).
  • No reset() / current() / end() / key(), json_decode(), trim() or ucfirst() call in src/ (the reset() matches in tests are ProcessState::reset()).
• Pre-existing uses of PHP 8.3+ functions: none in src/ and tests/ (nothing relied on a transitive polyfill).
• CONTRIBUTING.md: new "PHP version" section.
• CHANGELOG.md: entry in the "Latest" section.

Checks

• Tests, highest dependencies (PHP 8.5): OK (61 tests, 127 assertions); with coverage (pcov, as the CI): OK, no risky test, lines 100% (78/78).
• Tests, lowest dependencies (--prefer-lowest, PHP 8.2): OK (61 tests, 127 assertions), symfony/polyfill-php83, -php84 and -php85 installed.
• PHPStan: no errors.
• PHP-CS-Fixer: no change.
• Rector: no change.

Requirements

• Documentation updates
  • Reference
  • Changelog
• Unit tests

Breaking changes

None: three new small dependencies (polyfills), no change of the minimum PHP version.
