Molten Code hardening, dispatch UX fixes, and SEO polish.

Refactored federation and smoke command tooling to share new `internal/cmdutil` JSON request/parse helpers, reducing duplicated HTTP handling code across CLI probes.

Added pre-agent GitHub preparation with automatic fork fallback so runs can initialize repositories even without direct upstream write access.

Fixed auth-gate token persistence/validation across Claude, Codex, Pi, and Auggie setup flows and added shared regression coverage.

Removed redundant Claude setup pre-step, simplified onboarding controls, and tightened Hub runtime configuration/base-URL normalization paths.

Updated runtime packaging to include Go SDK in the container image and aligned Docker packaging tests with the new layout.

Patched harness failure-follow-up and clone-error handling paths while polishing Hub UI layout/status visuals (widescreen, CPU/MEM/I/O, icon states).

Published the 2026-04-20 UTC release rollup in `src/data/releases.json`.

Added edge-function canonical URL redirects for `/`, `/blog/*`, `/login/*`, and `/pricing/*`, including Product Hunt ref stripping and hub-login target normalization.

Updated `/code` onboarding to a single-image Docker command and added harness hover/focus accent behavior for supported runtimes.

Updated `/hub` ranking and provider logo mapping (CI/GitHub, Codex, Auggie, Claude) with new unit coverage.

Refined homepage title copy by removing the "Powered by OpenClaw" suffix.

Preserved Recent Activity card expand/collapse state across feed refreshes so opening an item no longer auto-collapses on rerender.

Simplified Activity panel copy and open/close controls for faster task/event scanning in dispatch dashboard.

Logged explicit task completion/failure events and added structured caller payload fields (`Failure`, `Error details`) for downstream failure parsing.

Centralized connected-agent display/emoji/skills/presence helpers in app layer to reduce duplication across service and web handlers.
