* fix: resolve blocking commands with null on timeout instead of hanging

- Blocking commands (BLPOP, BRPOP, BZPOPMIN, XREAD, etc.) now resolve
  with `null` when their timeout expires without a response, matching
  Redis behavior and preventing indefinite hangs during undetectable
  network failures

- Added `blockingTimeout` option as a safety net for commands that
  block forever (timeout=0 / BLOCK 0)

- Automatically extracts and tracks timeout from command arguments,
  adding a 100ms grace period for finite timeouts

- Protects commands in both offline queue and command queue with
  absolute deadline tracking

- Simplified setBlockingTimeout API to resolve with null (no callback,
  no error rejection)

* refactor(command): move blocking timeout extraction to Command class

* fix: blocking timeout reamde and add more unit tests

* test: add more unit and functional tests

* feat: add configurable blockingTimeoutGrace option
