fix(driver-abcip-cli): resolve Low code-review findings (Driver.AbCip.Cli-003,004,005,006,007,008)

- Driver.AbCip.Cli-003: SubscribeCommand prints the 'Subscribed' banner
  BEFORE wiring OnDataChange so the main thread can't interleave its
  write with the poll-thread handler.
- Driver.AbCip.Cli-004: AbCipCommandBase.Timeout and SubscribeCommand
  validate TimeoutMs / IntervalMs and throw CommandException on
  non-positive values.
- Driver.AbCip.Cli-005: every command now calls FlushLogging() in its
  finally block.
- Driver.AbCip.Cli-006: Timeout init throws NotSupportedException with a
  pointer at TimeoutMs instead of silently swallowing assignments.
- Driver.AbCip.Cli-007: added AbCipCommandBaseTests covering BuildOptions
  shape, probe / controller-browse / alarm toggles, host address, family
  selection, tag list passthrough.
- Driver.AbCip.Cli-008: rewrote the opening paragraph in
  docs/Driver.AbCip.Cli.md to credit the six-CLI roster with a pointer
  at docs/DriverClis.md.
