release: v0.18.0 — composite both-plane Bifrost binding (#18 closed)

Publishing-minor for the #18 arc: ratatoskr now exposes a COMPOSITE Bifrost
endpoint (build_combined_app, :8392) so one bound Worldtree session drives BOTH
the memory.* and affect.* planes through a single endpoint — completing the
Tier-3 consumer round-trip (durable memory + live PAD from one binding).

Shipped as patches v0.17.15 (affect.fetch prerequisite) → v0.17.16 (composite) →
v0.17.17 (#17 op-feed fix); this minor publishes the milestone.

Live-smoke (against real stores + bifrost 0.10.0 on a running :8392): handshake
grants BOTH caps by store presence; the PAD read route serves real sindra PAD;
both planes dispatch through the one endpoint at a single bound session_id with
the op-feed deriving plane per path. The remaining WT-driven turn is gated on
infra-ops adding :8392 to Worldtree's BIFROST_CLIENT_ALLOWED_HOSTS (requested).
