refactor(runtime): share Jakarta adapters across runtimes

[youngledo]

Summary

• add jfoundry-jakarta with portable jfoundry-web-jaxrs, jfoundry-transaction-jta, and jfoundry-domain-event-jta modules
• delegate Quarkus and Helidon transaction, domain-event, and HTTP logging behavior to the shared implementations while retaining runtime-local CDI/provider/build-time integration
• preserve original Exception and Error failures when JTA rollback, rollback-only, timeout reset, or transaction resume cleanup also fails
• use Java 25 ScopedValue for the lexically bounded JTA domain-event scope and Math.clamp for bounded HTTP body capture
• document failure-cleanup, contextual-state, and runtime logging-facade rules in AGENTS.md and the framework maintenance skill
• manage the new artifacts and portable API versions, enforce Jakarta module dependency boundaries, and update the bilingual architecture documentation and module diagram

Verification

• ./mvnw -pl jfoundry-runtime/jfoundry-jakarta/jfoundry-transaction-jta,jfoundry-runtime/jfoundry-jakarta/jfoundry-domain-event-jta -am test
• ./mvnw -pl jfoundry-runtime/jfoundry-jakarta/jfoundry-web-jaxrs,jfoundry-runtime/jfoundry-quarkus/runtime/jfoundry-quarkus-runtime,jfoundry-runtime/jfoundry-helidon/runtime/jfoundry-helidon-runtime -am test

Compatibility

Existing Quarkus and Helidon public runtime entry-point class names, configuration keys, and runtime behavior remain unchanged. Runtime modules gain managed transitive dependencies on the shared Jakarta implementation artifacts. Cleanup failures are now attached as suppressed exceptions instead of replacing an existing primary failure. Spring and WebClient support are unchanged.
