Function normalize_advisor_note 

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

Unstable (feature: advisor) — may change or be removed

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`.
