v2.0.5: consistency check + test picker cleanup

fix(picker): a selection tap toggles the row, no click-through as on …

v2.0.1: Maximum performance with cleaner code

ref: cleanup structure and comments

- comments must be meaningful and readable - 2 sentences or 1.5-line bullet
  points
  - Bullets max 1.5 lines (~100 expanded columns); paragraphs max 2 short sentences.
  - No ; or : as sentence splitters — reformulate into plain sentences rather than splitting into more text (or count both sides as one sentence).
  - No duplicate or obvious information; code already shows it, don't repeat it.
  - No comments/typedocs everywhere — only where it makes sense; no intro sentences, just raw purpose in complex code.
  - No name restatement, no legacy/history words ("legacy", "old", "the former", "rewrite").
- ensure best coding practices are upheld - no multi-purpose classes

This release fixed all uses of directories in Android 10+. Additionaly fixes subject creation.
