Synthesize a regex from examples

Installpip install "git+https://github.com/Jinversedigital/jiangkit" (base install)

$ jiang experimental regex_from_examples -p 2026-09-27 -p 1999-01-05 -p 2024-12-31 -n 2026/09/27 -n 27-09-2026 -n hello
regex (full match): \d{4}-\d{2}-\d{2}
anchored form     : ^\d{4}-\d{2}-\d{2}$
accuracy          : 100.0% on 3 positive / 3 negative examples

這個正規表示式要求「整個字串」從頭到尾依序符合：
  1. 剛好 4 個數字（0–9）
  2. 一個連字號「-」
  3. 剛好 2 個數字（0–9）
  4. 一個連字號「-」
  5. 剛好 2 個數字（0–9）
