v3(b1-abcip): RawPath read-path for AbCip (multi-device)

Apply the reviewed Modbus exemplar to the AbCip multi-device driver:
- Mapper AbCipEquipmentTagParser -> AbCipTagDefinitionFactory; TryParse -> FromTagConfig(tagConfig, rawPath, out def); drop leading-{ heuristic + the deviceHostAddress key; add inverse ToTagConfig; round-trip arrays/members/safety for coverage.
- Options: Tags (typed) -> RawTags (RawTagEntry list); Devices list kept.
- Driver: byName-only resolver over _tagsByRawPath (Ordinal); table built from RawTags via FromTagConfig, threading entry.DeviceName (device routing key) + entry.WriteIdempotent onto the def. Multi-device routing keys on DeviceName-or-host via a _devicesByRoutingKey index; discovery groups _declaredTags by RoutesToDevice.
- Factory: retire the pre-declared Tags DTO/BuildTag; bind List<RawTagEntry> RawTags.
- Probe: derive probe tag path from RawTags via the mapper.
- Cli BuildOptions projects typed tags -> RawTagEntry (ToTagConfig).
- Tests: AbCipRawTags helper (typed def -> RawTagEntry); parser tests -> FromTagConfig; blob-fallback driver tests rewritten to author via RawTags + read by RawPath. Driver.AbCip.Tests 342/342, Cli.Tests 42/42.

TODO(v3 WaveC): DeviceName becomes a pure logical name once the device connection host moves to the Device row's DeviceConfig.
