v3(focas): adopt Modbus RawTagEntry exemplar (multi-device)

- Rename FocasEquipmentTagParser -> FocasTagDefinitionFactory; TryParse ->
  FromTagConfig(tagConfig, rawPath, out def). Drop leading-{ heuristic + the
  deviceHostAddress blob key; def.Name = rawPath. Add inverse ToTagConfig.
  writable: absent -> read-only, explicit true honoured (note preserved).
- FocasDriverOptions.Tags -> RawTags (IReadOnlyList<RawTagEntry>).
- FocasDriver: _tagsByRawPath (Ordinal); byName-only resolver; build table from
  RawTags via FromTagConfig; multi-device routing threads RawTagEntry.DeviceName
  -> ResolveDeviceHost match against options.Devices -> def.DeviceHostAddress
  (TODO v3 WaveC: live host from Device row DeviceConfig). Tolerant per-tag
  skip+log (mapper/address/matrix miss -> BadNodeIdUnknown); unknown device
  fails init fast.
- Factory: bind List<RawTagEntry> RawTags; retire FocasTagDto/ParseDataType.
- CLI FocasCommandBase.BuildOptions -> RawTags via ToTagConfig + DeviceName.
- Tests: FocasRawTags helper; migrate Tags= -> RawTags=; rename parser tests to
  FromTagConfig; rewrite retired blob-ref tests (equipment-tag/capability-gate/
  resolve-host) onto authored RawPath. 272 driver + 52 CLI green.
