Hub setup surge, OpenClaw 2026.4.9 bump, and web polish.

Bumped the OpenClaw repository version marker to 2026.4.9 for the coordinated runtime release cadence.

Aligned container-pinned OpenClaw version metadata to 2026.4.9 so container/runtime bundles stay in sync.

Expanded command and core helper test coverage across smoke/federation flows, auth, long-polling, store helpers, and realtime handler utilities.

Strengthened failing-log remediation expectations in smoke tests so root-cause follow-up task behavior is explicitly validated.

Shipped major Hub setup capabilities including dock-driven connect/apply flow, task clone actions, PR-merge monitoring, and richer prompt submission feedback states.

Refined Hub UX and runtime visibility with compact metric hovers, disk throughput readouts, GitHub profile/menu integrations, contributor-default repos, and onboarding readability updates.

Fixed Hub reliability edge cases across existing-token verification, connected indicator state, no-change task handling, source-task closing, and failure follow-up repository targeting.

Overhauled Hub Add Agent/Company surfaces with clearer runtime guidance, responsive section layouts, refreshed onboarding copy, and updated brand icon treatment.

Fixed rotated-token copy interactions and related API/test coverage so key-copy actions stay clickable and deterministic.

Launched a richer /code page with product screenshots, runtime walkthrough content, and copy-friendly container command examples.

Refined brand/SEO presentation via display-name preference helpers, hub directory metadata polish, and Docker Hub profile links moved to moltenai.

Polished the 404 experience and removed transient prompt-image artifacts to keep website assets cleaner.
