v1.0.3

Fixed

• Local docker-compose stack could not boot after the core consolidation.
  Migration 001 now references the shared core.person/core.chat, but the
  bundled dev Postgres had no core schema, so docker-compose up crash-looped
  (schema "core" does not exist). Added deploy/core-init.sql (a minimal local
  core schema + core.touch) mounted via docker-entrypoint-initdb.d, and set
  search_path=branchy on the compose DATABASE_URL. Production is unaffected
  (it uses the real shared core-postgres); this only fixes local development.
