Release v1677

Automated release from CI pipeline

Changes:
chore: extract ruv-neural to ruvnet/ruv-neural, wire as submodule (#1019)

The 12-crate brain-topology analysis ecosystem (v2/crates/ruv-neural) was a
self-contained nested workspace with no inbound deps from the v2 workspace
(verified: zero path references outside its own tree). Published standalone
at github.com/ruvnet/ruv-neural and re-attached here as a submodule at the
same path, so the build layout is unchanged while the project gets its own
repo/CI/release cadence.
