01 what the model was asked

Create textstats.py, a small text-statistics module with exactly these three functions:

1. word_count(text: str) -> int
   Words are maximal runs of ASCII letters, digits, and apostrophes (regex [A-Za-z0-9']+). Return how many words text contains. Empty or word-free text returns 0.

2. top_words(text: str, n: int) -> list[tuple[str, int]]
   Count words case-insensitively (lowercase them). Return the n most frequent (word, count) pairs, most frequent first; break count ties alphabetically by word.

3. reading_time(text: str) -> int
   Estimated minutes to read at 200 words per minute, rounded up, with a minimum of 1 (even for empty text).

Use only the Python standard library.
