Regenerate export files (dataset, statistics, mentions) with 146 active users and 4778 total contributions, reflecting new user activity and updated rankings. Add new comments-per-day, comments-per-hour, and comments-per-weekday graphs covering the period from 2024-11-07 to 2024-12-06, and remove the old dataset.txt file.
Update the export statistics dataset to include 43 additional posts across existing user files (AceDev, AlgoRythm, AdamOnAir, posts-12bitfloat) and add two new user export files for AmyShackles and BlueNutterfly. The 0_dataset.txt summary now reflects 146 total lines (up from 114) with updated contribution percentages and average post lengths. Binary export artifacts (whl, tar.gz, db, graph pngs) are rebuilt to match the refreshed data.
