Thread Pool Example

This example is a self-contained test suite that exercises the full public API of espp::ThreadPool across a range of usage patterns, from basic single-pool operation to more advanced concurrent and multi-pool scenarios.

#	Test	APIs covered
1	Lifecycle	start(), stop(), is_running(), worker_count()
2	Normal dispatch	submit(), queue_size(), stats()
3	Bounded-queue rejection	try_submit() with deterministic barrier
4	Blocking submit	submit() with block_on_submit_when_full
5	Post-stop rejection	submit() after stop()
6	Concurrent lifecycle	multi-thread start() / stop() stress
7	Concurrent submission	multi-thread submit() + try_submit()
8	Chained pools	a job in pool_a submitting work into pool_b
9	Self-submit	a running job submitting back to its own pool

Each test logs individual PASS / FAIL results inline. At the end of the run a summary is printed:

==================== Results ====================
  PASS  lifecycle: start/stop/is_running/worker_count
  PASS  submit: normal dispatch + queue_size + stats
  ...
=================================================
9/9 tests passed
All tests passed!

The final summary line (N/N tests passed / N test(s) FAILED) is the key indicator of overall correctness and is suitable for CI log parsing.
