Final two of the five driver test clients. Closes out the #249 → #250 → #251 track.

otopcua-s7-cli

S7comm / ISO-on-TCP 102 against S7-300/400/1200/1500. All S7 data types incl. DateTime round-trip + bit/word/dword DB addressing. Documents the PUT/GET-must-be-enabled gotcha.

otopcua-twincat-cli

ADS against TwinCAT 2/3 runtimes. Full IEC 61131-3 atomic type set including WString + the four Time/Date variants. --poll-only toggles UseNativeNotifications=false. Subscribe banner announces mechanism (ADS notification vs polling).

Tests

49 new (22 S7 + 27 TwinCAT); 122 cumulative driver-CLI tests across #249 + #250 + #251.

Suite complete

5 CLIs shipped: otopcua-{modbus,abcip,ablegacy,s7,twincat}-cli. Every driver family has a shell-level ad-hoc validation tool.

Test plan

Full-solution build clean. Both --help outputs verified.

Task #251 — S7 + TwinCAT test-client CLIs (driver CLI suite complete) 4dc685a365

Final two of the five driver test clients. Pattern carried forward from
#249 (Modbus) + #250 (AB CIP, AB Legacy) — each CLI inherits Driver.Cli.Common
for DriverCommandBase + SnapshotFormatter and adds a protocol-specific
CommandBase + 4 commands (probe / read / write / subscribe).

New projects:
  - src/ZB.MOM.WW.OtOpcUa.Driver.S7.Cli/ — otopcua-s7-cli.
    S7CommandBase carries host/port/cpu/rack/slot/timeout. Handles all S7
    atomic types (Bool, Byte, Int16..UInt64, Float32/64, String, DateTime).
    DateTime parses via RoundtripKind so "2026-04-21T12:34:56Z" works.
  - src/ZB.MOM.WW.OtOpcUa.Driver.TwinCAT.Cli/ — otopcua-twincat-cli.
    TwinCATCommandBase carries ams-net-id + ams-port + --poll-only toggle
    (flips UseNativeNotifications=false). Covers the full IEC 61131-3
    atomic set: Bool, SInt/USInt, Int/UInt, DInt/UDInt, LInt/ULInt, Real,
    LReal, String, WString, Time/Date/DateTime/TimeOfDay. Structure writes
    refused as out-of-scope (same as AB CIP). IEC time/date variants marshal
    as UDINT on the wire per IEC spec. Subscribe banner announces "ADS
    notification" vs "polling" so the mechanism is obvious in bug reports.

Tests (49 new, 122 cumulative driver-CLI):
  - S7: 22 tests. Every S7DataType has a happy-path + bounds case. DateTime
    round-trips an ISO-8601 string. Tag-name synthesis round-trips every
    S7 address form (DB / M / I / Q, bit/word/dword, strings).
  - TwinCAT: 27 tests. Full IEC type matrix including WString UTF-8 pass-
    through + the four IEC time/date variants landing on UDINT. Structure
    rejection case. Tag-name synthesis for Program scope, GVL scope, nested
    UDT members, and array elements.

Docs:
  - docs/Driver.S7.Cli.md — address grammar cheat sheet + the PUT/GET-must-
    be-enabled gotcha every S7-1200/1500 operator hits.
  - docs/Driver.TwinCAT.Cli.md — AMS router prerequisite (XAR / standalone
    Router NuGet / remote AMS route) + per-command examples.

Wiring:
  - ZB.MOM.WW.OtOpcUa.slnx grew 4 entries (2 src + 2 tests).

Full-solution build clean. Both --help outputs verified end-to-end.

Driver CLI suite complete: 5 CLIs (otopcua-{modbus,abcip,ablegacy,s7,twincat}-cli)
sharing a common base + formatter. 122 CLI tests cumulative. Every driver family
shipped in v2 now has a shell-level ad-hoc validation tool.
