Add ecosystem manifest protocol, EcosystemBridge class, server proxy
routes, port/event integration for folk-rapp, sandboxed iframe mode
with origin-validated postMessage, and SW caching for ecosystem modules.
Security: no allow-same-origin on sandboxed iframes, redirect: error
on proxy fetches, origin validation on all postMessage handlers.
