ci: sync workflows with kariricode-sanitizer pattern (ARFA 1.3)

code-quality.yml:
- Add 'Patch phpunit.xml.dist' step to analyse and tests jobs
  (fixes beStrictAboutCoverageMetadata false-positive warnings)
- Update job name to 'PHPUnit Tests (pcov)' with 181 tests baseline
- Fix quality summary title: KaririCode Transformer (was Sanitizer)
- Fix summary table: 'PHPUnit Tests (pcov)' metric label

release.yml:
- Add 'Patch phpunit.xml.dist' step (was missing, present in sanitizer)
- Update release name/body for transformer (32 rules, 47 classes,
  181 tests, 482 assertions, 0 runtime deps, PHP 8.4+)
- Add Quick Start example with Transform attribute

-            PHP 8.4+ transformer engine — **zero external dependencies**, ARFA 1.3 compliant.
+            Composable, rule-based data transformation engine for PHP 8.4+.
+            32 built-in rules across 7 namespaces, `#[Transform]` attribute-driven
+            pipelines, zero runtime dependencies, and 100% test coverage. **ARFA 1.3 compliant.**
 
             ## Installation
