fix(client-cli): resolve Low code-review findings (Client.CLI-002,003,004,006,007,008,009,010)

- Client.CLI-002: SubscribeCommand's neverWentBad list now requires the
  node to be present in lastStatus (i.e. received at least one update)
  so the 'suspect' bucket only contains observed nodes.
- Client.CLI-003: every long-running command validates numeric option
  ranges (Interval / Depth / MaxDepth / Duration / Max) and throws
  CliFx CommandException on out-of-range values.
- Client.CLI-004: SubscribeCommand carries XML summary docs on the
  type, ctor, every [CommandOption] property, and ExecuteAsync —
  matching the sibling commands' style.
- Client.CLI-006: HistoryReadCommand parses --start / --end with
  InvariantCulture+UTC and surfaces FormatException as CommandException;
  every NodeIdParser.ParseRequired call wraps FormatException /
  ArgumentException as CommandException.
- Client.CLI-007: CommandBase.ConfigureLogging calls Log.CloseAndFlush()
  before assigning a new Log.Logger so prior sinks are disposed.
- Client.CLI-008: rewrote the subscribe and historyread sections of
  docs/Client.CLI.md (every flag documented, summary-bucket vocabulary,
  StandardDeviation aggregate, UTC --start/--end convention).
- Client.CLI-009: SubscribeCommand / AlarmsCommand use named local
  handlers and detach them via -= after UnsubscribeAsync so no
  notification reaches the console after the command's output phase
  ends.
- Client.CLI-010: added CommandRangeValidationTests,
  EventHandlerLifecycleTests, InputValidationErrorsTests,
  LoggerLifecycleTests, and SubscribeCommandSummaryTests pinning every
  Low fix; FakeOpcUaClientService gained AddDiscoveredVariable +
  RaiseDataChanged + BrowseResultsByParent helpers.
