Adding investors to a raise

Two doors into the same room:

• Match scores the graph against your raise and shows the best-fit firms first. Pulling one onto the raise is a reveal.
• Your relationship book (/app/investors) holds everyone you already know. Add them to a raise directly; that never counts as a reveal.

Once an investor is on a raise, enrichment runs automatically: partner rosters, contact details, and (when connected) Signal coverage.
