Both-add unions: pipeline registry rows (azure/azure_ai/azure_ai_anthropic
beside the google rows), ChunkDialect literal now carries azure + gemini,
the thinking-delta placeholder arm keeps gemini split from the
anthropic|openai|azure arm (all placeholder arms are removed by the
ChunkDialect split fix later in this branch). CLAUDE.md scope/tree
hand-unioned for ten providers. DIFFERENTIAL_REPORT.md regenerated on the
merged tree (0 divergent). RESPONSE_FORMAT_SPOOF_MODEL rename merged clean
(identical hunk on both branches).
