Initial commit: note-taking/task-tracking app with LLM integration scaffold

Vue 3 + TypeScript frontend with Pinia stores, markdown rendering (marked + DOMPurify),
wikilink/tag linkification, and autocomplete. Quart async backend with SQLAlchemy 2.0,
PostgreSQL ARRAY columns, task-note companion linking, backlinks, and note-to-task
conversion. Docker Compose setup with PostgreSQL 16 and Ollama.
