Added

• Authentication. Sign in with your Abyssale account via OAuth — no API keys to copy around. Access is scoped per client: you can, for example, allow a client to read your designs without allowing it to spend generation credits. See Authentication.
• Identity — get_me: check which Abyssale workspace you're connected as.
• Discovery — list_designs, search_designs, get_design, get_design_format, get_design_as_import, list_projects, create_project, list_fonts, get_remaining_credits: browse and inspect your designs, projects, fonts and credit balance.
• Generation — generate_static_banner for a single image on demand, plus generate_banners_async, generate_multipage_pdf and check_generation_status for multi-format, video, and multi-page output.
• Design import — import_design_from_json and check_design_import_status: create a design from a JSON structure, including support for images that live on your own machine.
