Subject: Engine: Add buildIndexMappings() helper (single typeless mapping)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Single 'properties' block, documentType as a keyword field inside it,
no include_in_all anywhere (the field was removed in ES 6).
Relationships emit as keyword fields with doc_values: false, matching
the bundled engine's ES-5-mode behavior. Field-data multi-analyzer
shape (raw, keywords, stems) preserved.
