/**
 * Pure helpers for `extract-sharepoint-links-in-mail`.
 *
 * `extractSharepointUrls(htmlBody)` finds every `https://*.sharepoint.com/...`
 * URL inside an HTML mail body — both `<a href=...>` and bare-text
 * occurrences — and returns the deduplicated list.
 *
 * `buildShareToken(url)` encodes a URL for Graph's `/shares/{token}`
 * resolver per [shares-get](https://learn.microsoft.com/en-us/graph/api/shares-get):
 * `u!` + base64url(url) with no padding.
