ci: adopt estate reusable CI + split 300-line violations (v0.22.0)

- ci.yml → thin caller of peptide-e2e reusable CI (tests: brain-monkey)
  + keep check-constants as parallel job; workflow_call trigger enabled
- deploy.yml: retire standalone validate job; gate on ci.yml via workflow_call
- composer.json: add 'test' script (vendor/bin/phpunit --testdox)
- Version bumped to 0.22.0

300-line splits (9 files over limit → all under 300):
- class-keyword-extractor.php: shared tokeniser from Idea_Scorer + Semantic_Dedup
- class-image-aspect-ratio.php: aspect-ratio snap from OR provider + OR batch
- class-settings-sanitizer.php: option sanitization from Admin_Page
- class-settings-fields-images.php: image fields from Settings_Fields_Extended
- class-runware-image-validator.php: credential check from Runware_Image_Provider
- Runware batch: 15 phpcs:disable lines → 1 grouped suppression

+#
+# Thin caller that delegates to the reusable estate CI workflow in peptide-e2e.
+# workflow_call is required so deploy.yml can gate on this workflow via
+# `uses: ./.github/workflows/ci.yml` (the workflow_call trigger enables that).
+#
+# Permissions: contents: write is required at the caller level so the reusable
+# workflow's phpcbf auto-commit job can push fixes back to the PR branch.
+# (GitHub enforces that callers cannot be escalated beyond their declared scope.)
+#
+# tests: brain-monkey — no WP install or DB required; Brain Monkey mocking only.
+# line_limit_paths: includes — estate hard 300-line rule applied to includes/.
