Milestone 2 of the Configuration Engine sprint.
- Add schema/validators/primitives: pure isValidHexColor/HttpUrl/Email,
validateJson, validateCss, extractStyleBlocks, normalizeRoute. One function
per concern, no duplicated validator logic.
- Refactor ProjectValidator to compose the primitives and tag every issue with
section + fieldKey + severity ('error' blocks publish, 'warning' advisory).
Preserves all existing codes/messages; adds duplicate-routes, invalid-css,
invalid-widget-config checks.
- Facade: issuesByField, issuesBySection, blockingIssues, hasBlockingIssues;
publish() now gates on severity==='error' instead of any issue.
- i18n: add validationInvalidJson/Css/DuplicateRoutes/InvalidWidgetConfig to
the Translations interface + en/ru/hy.
- Specs: primitives + ProjectValidator (25 passing total).
Gate: tsc --noEmit, npm test (25/25), arch:check, build all green.
