feat: add reaffirmation and normalizedScore fields to SearchResult (PM-14a)

SearchResult model now includes:
- reaffirmation: multiplicative reaffirmation factor (replaces additive occurrenceBoost)
- normalized_score: per-batch normalization to [0.0, 1.0] (PM-13)

Both fields have defaults (1.0 and 0.0) so existing API responses without
them are handled gracefully. occurrenceBoost kept for back-compat (PM-14b).

Bump version 0.2.2 → 0.3.0 (new fields = minor version).
