Makes slice 1 clickable and real. The effect DRIVER now PERFORMS action-effects (closing the loop):
a 'relate' effect {:args (src kind dst)} mutates the relation graph. The events calendar behavior's
allocate-link DAG emits (effect relate (field target) 'allocated' (field slug)), so an allocated post
becomes a real main--allocated-->post edge on events (not just a log line).
UI: every blog post page shows an 'Allocate to a calendar' form (host/blog--allocate-form, shown when
a peer is configured) → POST /:slug/allocate reads the form field. events gets a /calendars page
listing posts allocated to 'main'. serve.sh seeds a 'main' calendar (is-a calendar) on events.
LIVE: submit the allocate form on blog.rose-ash.com/welcome → events /calendars shows 'welcome'
allocated to main, a real federated relation. blog 218/218.
