Der Button, der aus „Problem erkannt" ein „Problem gelöst" macht: startet eine interaktive Claude-Session, die dem Nutzer beim Einrichten hilft.
## Warum externes Terminal
Der ConPTY-Stack (`PtyTerminalSession`, `ConPtyPaneView`) liegt in `ClaudeDo.Ui` und ist Avalonia — der Installer ist WPF und referenziert nur Data/Releases/Localization. Beim Fresh Install sind `app\`/`worker\` außerdem noch n

Re-runs the environment checks against the installed configuration
(worker.config.json + detected install dir) without blocking navigation
and without auto-running on window open, only on a "Recheck" click.
Extracted the check-row rendering and check-run logic (busy state,
summary, Recheck command) out of SystemCheckPage into a shared
Checks/CheckListViewModel + Checks/CheckListView, composed by both
SystemCheckPage (wizard) and the new DiagnosePage (settings) instead
of duplicating it.
Adds a new wizard page (positioned right after Welcome, FreshInstall only)
that auto-runs EnvironmentCheckService on entry and shows one row per check
with status icon, localized title/message, and hint+help-link on
failure/unknown. A "Recheck" button re-runs it, guarded against re-entrancy.
IInstallerPage gets a BlocksNavigation default member; WizardViewModel's
Next button now binds to CanGoNext, which the current page can veto (used
here while a check run is in flight or a blocking Error+Failed result is
present — Warnings and Unknown results never block). The summary line names
the blocking checks so a disabled Next is self-explanatory.
Wires up DI for the check pipeline (IProcessRunner, IPortOwnerResolver,
per-run ClaudeCliLookup) and adds the checks.* / installer.systemCheck.*
locale keys in en.json + de.json.
Visual appearance is NOT verified — needs a manual pass in the running
installer.
