Dispatch UX cleanup, Hub workflow fixes, and 2026.4.14 bumps.

Bumped OpenClaw to 2026.4.14 and added Docker release workflow wiring so published images can track the coordinated runtime release cadence.

Updated the container's OpenClaw and MoltenHub plugin version pins, refreshed config-generation coverage, and reduced the image footprint by removing the bundled chat-proxy assets.

Reworked bundled tier definitions and startup/config scripts so the slimmer container layout still exposes the intended packaged capabilities.

Kept finished tasks visible while PR monitoring settles, removed stale studio hero clutter, and tightened current-work copy so Hub task state stays easier to follow.

Strengthened failure follow-up prompting to inspect failing log paths and root causes first, with updated harness and prompt coverage around the remediation flow.

Centralized harness auth-gate state and refreshed multiple task-library prompts so shared auth handling and built-in workflow templates stay more consistent.

Restored connected-agent selection and Hub delivery decoding behavior so Dispatch can reliably surface available workers, emoji/display-name metadata, and live connectivity state.

Polished the Dispatch interface with tighter header branding, dismissible onboarding help, cleaner card layouts, and more compact queue/compose alignment.

Removed outdated worker, bind-token, and skill-loading helper copy while simplifying unused local state and CI paths, backed by broader service and web test coverage.

Published the 2026-04-13 UTC release rollup and added release-page project metadata for MoltenHub Dispatch so the website can surface the new daily summary cleanly.
