A2A routing, chat landing, env config, and site SEO.

Shared library agent instructions into packaged runtime contexts so seeded agents receive the repository guidance they need during task execution.

Applied environment variables to harness and runtime application configuration, with config-script coverage for persisted settings.

Simplified task-list GitHub status display so only one GitHub action appears at the final stage.

Added a chat-first agent landing page with route, Dock, auth callback, and session-storage updates so app entry can open directly into agent chat.

Preserved login query parameters through auth callback redirects and aligned the chat page title format with the rest of the app.

Removed the blocking external font dependency and added font-loading regression coverage for faster, more reliable page rendering.

Published the April 27 release rollup and improved release project links so cards and detail pages route to the right product destinations.
