Auto-managed PR — Mode B (autonomous)

Driver: abcip Phase: 1 Plan PR: 1.2
Plan: docs/plans/abcip-plan.md
Effort: M Cross-driver: False

Summary

Today AbCipDataType.String flattens any Logix STRING UDT into a .NET string via libplctag GetString(0). Logix programs commonly define STRING_20/40/80 variants. Add StringLength field to AbCipStructureMember and AbCipTagDefinition, thread into the libplctag string-cap hint. Investigate libplctag's str_max_capacity / str_count_word_bytes attributes; extend LibplctagTagRuntime if needed.
