Joseph Doherty aafb9d4929 v3(b1-modbus): RawPath identity seam — RawTagEntry-driven Modbus driver
Wave-B EXEMPLAR. Retire the pre-declared/blob-parse tag model; the driver now
builds its RawPath -> definition table from the artifact's RawTagEntry set via a
pure mapper.

- Contracts: rename ModbusEquipmentTagParser -> ModbusTagDefinitionFactory;
  TryParse(reference) -> FromTagConfig(tagConfig, rawPath) (def.Name = rawPath,
  no leading-brace heuristic); add inverse ToTagConfig(def) serializer; keep all
  strict-enum reads + guards; also read stringByteOrder/deadband/coalesceProhibited
  so a RawTagEntry round-trips the full authored def. Inspect() unchanged.
- Options: Tags(IReadOnlyList<ModbusTagDefinition>) -> RawTags(IReadOnlyList<RawTagEntry>).
- Driver: _tagsByName -> _tagsByRawPath (Ordinal); resolver byRawPath-only; build
  the table from RawTags at Initialize threading entry.WriteIdempotent onto each def;
  Discover/Teardown updated.
- Factory: remove ModbusTagDto/BuildTag/ValidateStringLength + ConfigDto.Tags; bind
  RawTags from driver-config JSON.
- CLI ModbusCommandBase.BuildOptions: serialise typed defs -> RawTagEntry via ToTagConfig.
- Tests: migrate Tags= -> RawTags via ModbusRawTags.Entries helper; parser tests ->
  FromTagConfig(rawPath); factory String-length/enum tests re-seated on the mapper seam.
- Propagated rename to ControlPlane EquipmentTagConfigInspector (outside Modbus projects).

Modbus.Tests 315/315, Addressing.Tests 161/161, Cli.Tests 72/72 green.
Docker-gated Driver.Modbus.IntegrationTests left untouched (won't compile against
the new API; expected).
