Description: Provides S4 classes and methods for storing dense and sparse
    matrices in 'DuckDB' databases. The package supports constructing
    database-backed matrices from base R and 'Matrix' objects, extracting
    slices and summaries, performing arithmetic and selected linear algebra
    operations, and materializing results for larger-than-memory workflows.
    It integrates with 'dbProject' to keep database paths, live connections,
    and lazy matrix tables synchronized across interactive analyses.
