Ullrich Schäfer bf907976c4 docs: split-domain handles idea + interop constraint for the trails check
Prompted by Hollo's split-domain setup. Two parts:

- docs/ideas/split-domain-handles.md: offering split handle/server
  domains to self-hosters is config-level work — Fedify's origin
  option natively accepts { handleHost, webOrigin } — and handles are
  permanent identity, so apex handles matter. Single-domain stays the
  default (Decision #18); post-launch polish.
- Interop constraint pinned in social-federation task 6.1 and
  route-federation's gating decision: the trails-to-trails NodeInfo
  check must run against the actor IRI's host after WebFinger
  resolution, never the handle's domain — split-domain remote
  instances would otherwise be wrongly refused.
