DefaultCandidateSearchers

Factory for creating default candidate searcher chains.

The default chain is ordered cheapest-first:

1. By ID lookup (instant)

2. Exact name match (instant)

3. Normalized name match - "Dr. Watson" -> "Watson"

4. Partial name match - "Brahms" -> "Johannes Brahms"

5. Fuzzy name match - handles typos

6. Vector/embedding search (moderate)

Java usage:

List<CandidateSearcher> searchers = DefaultCandidateSearchers.create(repository);
