fix(driver-ablegacy-cli): resolve Low code-review findings (Driver.AbLegacy.Cli-002,003,004,005,006,007)

- Driver.AbLegacy.Cli-002: WriteCommand.Value description lists the full
  true/false, 1/0, on/off, yes/no alias set.
- Driver.AbLegacy.Cli-003: SubscribeCommand serialises every WriteLine
  via a per-execution consoleGate lock so the poll-thread OnDataChange
  handler can't interleave with the banner.
- Driver.AbLegacy.Cli-004: dropped 'await using var driver' in favour of
  a plain 'var driver' + explicit await ShutdownAsync in finally; the
  driver is no longer shut down twice.
- Driver.AbLegacy.Cli-005: SubscribeCommand.IntervalMs description
  carries the PollGroupEngine 250ms-floor caveat; docs/Driver.AbLegacy.Cli.md
  spells out the same.
- Driver.AbLegacy.Cli-006: ProbeCommand --type now carries the short
  alias 't' to match the other commands.
- Driver.AbLegacy.Cli-007: BuildOptionsTests cover the probe-disabled,
  device-shape, tag-passthrough, timeout-propagation, and empty-tag-list
  paths.
