M3 R3.2 SHIPPED: docs — AddHistoricalValuesAsync recorded in roadmap, plan, and CLAUDE.md surface

Marks M3 historical writes SHIPPED + live-validated across the roadmap (R3.2/R3.3/one-glance),
revision-write-path.md §"R3.1 CAPTURED", and the CLAUDE.md Required SDK Surface (the new write op,
gRPC-only, AddStreamValues "ON" path, Float-only, distinct from the still-blocked AddS2 streaming
path).
