feat: scaffold outreach engine monorepo on the novelpad-desktop stack

Workspaces: config (copied), outreach-core (schema + actions/queries +
hard gates), outreach-ai (Gemini client + embeddings copies, profiler and
mission-fit-judge agent stubs), outreach-worker (DBOS executor with
nightly ingest + hourly expiry workflows), outreach-review (RR7 review
queue v0). Initial drizzle migration incl. pgvector extension.

Stack contract: Yarn 4.5.0 + Turbo, Node 22.16, Drizzle 0.44.6 +
pgvector, DBOS 4.17.6, @google/genai on Vertex, gemini-embedding-001
@1536, React Router v7. Files copied from novelpad-desktop carry
provenance headers @ 62c56b87.
