Clean up and reorganize R libraries list

- Removed packages that are part of tidyverse (tibble, httr, jsonlite)
- Removed ragg graphics device package
- Reordered libraries: tidyverse first, then core packages, then extensions
- Improved descriptions to be more action-oriented and helpful
- Better logical grouping: data science core → visualization → time series
