.gitignore extended for TypeScript/Node build artifacts on top of the
prompts-repo template. .editorconfig and .prettierrc match the prompts
template (4-space indents, prose-wrap always for markdown).
Reframes the project as the protocol foundation for a future Electron-based
Ente desktop client (the existing official clients are unsatisfactory).
Adds an API reference section with TypeScript declarations for every
exported name across crypto, auth, model, api, session, and Client modules.
Adds Phase 10 desktop-client TODO items so a future agent can pick up the
plan.
