v3(b1-twincat): apply Modbus exemplar pattern to TwinCAT (multi-device)
- Rename TwinCATEquipmentTagParser -> TwinCATTagDefinitionFactory; TryParse ->
FromTagConfig(tagConfig, rawPath, out def). Drop leading-'{' heuristic + the
deviceHostAddress key; def.Name = rawPath. Keep strict-enum + Inspect; add a
Structure guard (sole tag path now) + inverse ToTagConfig.
- Options: Tags -> RawTags (RawTagEntry); keep Devices + protocol fields.
- Driver: _tagsByRawPath (Ordinal); byName-only resolver; build table from
_options.RawTags via FromTagConfig, threading WriteIdempotent + DeviceName.
Multi-device: ResolveDeviceHost matches entry.DeviceName against options.Devices
(by name, then host) -> def.DeviceHostAddress (TODO(v3 WaveC): live host from the
Device row's DeviceConfig). DiscoverAsync now emits from the table.
- Factory: retire pre-declared tags[] DTO path; bind rawTags; keep Devices.
- Cli: BuildOptions serialises typed defs -> RawTagEntry via ToTagConfig.
- Tests: TwinCATRawTags helper; migrate Tags= -> RawTags=; rename parser tests to
FromTagConfig; equipment/resolve-host/array tests delivered via RawTags.
Gate: Contracts + Driver build green; Driver.TwinCAT.Tests 192 pass, Cli.Tests 70 pass.
