Function normalize_advisor_note 

pub fn normalize_advisor_note(note: &str) -> String

Case-insensitive, punctuation-folded normalization. Lowercases, applies NFKC, collapses every run of non-letter / non-digit characters into a single space, and trims — so "Stop.", "*Stop*", and " stop " all key to stop, while "No issue; continue." keys to no issue continue. omp normalizeAdvisorNote.
