/**
 * Librarian candidate scorer — computes a composite score for a knowledge
 * entry candidate to determine whether it should overwrite an existing entry.
 *
 * Score formula: `base × (0.7 + 0.3 × reliability) × expiryPenalty`
 *  - `base`          — the entry's raw confidence (0–100)
 *  - `reliability`   — source trust multiplier from `ConflictPolicy.sourceReliability`
 *                      (defaults to 0.5 for unknown sources)
 *  - `expiryPenalty` — 0.5× if `validUntil` is in the past, otherwise 1.0
