/**
 * Address tokenisation + match scoring — the canonical helper
 * reconciling four cohort implementations.
 *
 * Surveyed implementations:
 *
 *  - compass-mcp `src/tools/by-address.ts` `addressMatchesQuery` /
 *    `normalizeAddressForMatch` — NFKD diacritic strip, comma/slash
 *    collapse, street-type canonicalisation, token-equality, numeric
 *    token required.
 *  - homes-mcp `src/tools/by-address.ts` — relies on homes.com's own
 *    slug routing, with a post-hoc token-overlap check on the
 *    returned street_address.
 *  - onehome-mcp `src/tools/by-address.ts` — fuzzy normalisation
 *    via `joinNonEmpty` + comparison against reconstructed street
 *    parts.
 *  - redfin-mcp `src/resolve.ts` `scoreStreetMatch` — token-overlap
 *    scorer with a strict numeric-prefix anchor.
 *
 * Differences reconciled here:
 *
 *  - Compass requires EVERY query token to appear → too strict for
 *    redfin's autocomplete results where the candidate often drops the
 *    unit number.
 *  - Redfin scored 0..1 with a threshold of `>= 0.5` → too lax,
 *    accepts even tokens (homes #50 closed by tightening to `> 0.5`).
 *  - Homes drops short tokens (< 3 chars) at tokenise time so suffix
 *    abbrev noise vanishes ("Ln" / "St" never enter the score).
 *
 * Canonical policy:
 *
 *  1. Drop sub-3-char tokens (homes convergence) — absorbs USPS
 *     abbreviation drift without needing the SUFFIX_PAIRS table at
 *     this layer.
 *  2. Anchor on the leading numeric token (redfin's
 *     `scoreStreetMatch`) — street number MUST match exactly.
 *  3. Score = |query ∩ candidate| / |query| over the kept tokens.
 *  4. Threshold > 0.5 (strict majority) — homes #50.
