v0.170.0: root → Indítópult (302); Vezérlőpult at /dashboard; CLAUDE.md stale-note fix

/ now 302s to /launcher (ONE canonical URL per page — launcher body never served at /);
the Vezérlőpult keeps /dashboard + its nav slot (operator ruling, reversing v0.163.0).
Nav: Indítópult active on /launcher, Vezérlőpult href=/dashboard active there. Post-login
default (/) and the topbar logo (/) flow through the redirect; login target unchanged.
Repointed 2 dashboard-card tests /→/dashboard. Corrected the stale vacation/agent-DOWN
note in CLAUDE.md (agent is up at 192.168.0.162:8443).

Tests: 302 target+status, /dashboard 200, nav hrefs/active; red-proof verified.
