Auto-managed PR — Mode B (autonomous)

Driver: s7 Phase: 1 Plan PR: PR-S7-A1
Plan: docs/plans/s7-plan.md
Effort: M Cross-driver: False

Summary

Closes the NotSupportedException cliff for Float64/Int64/UInt64. Extend S7Size with LWord; teach parser to accept DBL/LD suffix. S7netplus has no native LD; falls back to byte-range reads with explicit big-endian conversion.
