Bump version; remove prompt SQL migrations

Bump package version to 2.2.3, delete obsolete prompt-related SQL migration files and their runner/cleanup scripts under app/api/prompt/sql (prompt_code, prospect_id, search_vector, type column, and empty/run helpers). Also update README heading from 'Getting Started' to 'Install & Use' and rename app/api/prospects/LinkedInConnections.csv to app/api/prospects/linkedin.csv to standardize naming. These changes remove unused migration artifacts and tidy repository structure.
