Installation and usage

Authoring guideline for DuckPQ/DuckTable-based Parquet storage in Quool. Covers DuckPQ initialization, table discovery and registration, CRUD operations (upsert/select/load/query), cross-table JOIN queries using the <table><sep><column> pattern, DataFrame attachment, and parquet compaction. Encourages using DuckPQ as the top-level database interface rather than operating on DuckTable in isolation.
