New S7DataType members WString/Char/WChar/Dtl/Date/Tod/Time/S5Time mapped onto existing
DriverDataType (String / DateTime / Int32 ms); writes refuse out-of-range with BadOutOfRange.
Optional localTsap/remoteTsap/connectionType through options, factory JSON, probe and AdminUI form.
NegotiatedPduSize snapshotted at connect and exposed via GetDiagnostics (DriverHealth has no bag).

Rename S7EquipmentTagParser -> S7TagDefinitionFactory; TryParse(reference)
-> FromTagConfig(tagConfig, rawPath, out def) (drops the leading-{ heuristic,
keys the def by RawPath, adds inverse ToTagConfig). Replace S7DriverOptions.Tags
(pre-declared S7TagDefinition list) with RawTags (IReadOnlyList<RawTagEntry>);
the driver builds its RawPath->def table from RawTags at Initialize via the
factory (skip+log on miss), resolver is byName-only, DiscoverAsync + init guards
+ address pre-parse now run off that table. Factory retires the pre-declared DTO
tag path (RawTags binding only). Cli BuildOptions serialises typed defs to
RawTagEntry. Tests migrated to a S7RawTags helper + FromTagConfig; parser test
files renamed. Coordinator's EquipmentTagConfigInspector S7 rename left to Wave-B
coordinator; Driver.S7.IntegrationTests (Docker-gated) left red per scope.
Driver.S7 + Cli build green; Driver.S7.Tests 264/264, S7.Cli.Tests 49/49.
Adds <summary>/<param>/<returns>/<inheritdoc> where missing and removes
project bookkeeping IDs (task/tracking refs) from shipped code comments,
so the docs read cleanly and CommentChecker is quiet except for known
false positives (PLC/protocol terms, event/IEqualityComparer inheritdoc).
Doc/comment-only; no logic changed; solution builds clean.
Introduces Driver.S7.Contracts (dependency-free POCO project) and moves
S7DriverOptions / S7ProbeOptions / S7TagDefinition / S7DataType into it.
Adds S7CpuType enum mirroring S7.Net.CpuType exactly (7 values with
explicit integer codes). Runtime S7CpuTypeMap bridges S7CpuType →
S7.Net.CpuType at the single Plc construction site in S7Driver.InitializeAsync.
S7DriverFactoryExtensions and S7CommandBase updated to use S7CpuType; test
files updated to match (S7_1500Profile, S7DriverScaffoldTests). AdminUI can
now reference Driver.S7.Contracts without pulling in S7netplus.
