Line Tools: Dedupe, Sort & Shuffle
Cleans up line-based text: removes duplicate lines (keeping the first occurrence), sorts alphabetically or numerically in either direction, reverses, shuffles, trims whitespace, drops empty lines and adds line numbers — operations you can stack in one pass.

Notes
- Natural sort treats digit runs as numbers, so "item2" sorts before "item10".
- Deduplication can be case-insensitive; the kept line is always the first one that appeared.
