ed 4a33848620 fix(io_pool): increase worker count from 4 to 8 to prevent test hangs
Root cause: test_full_live_workflow in batch context (with prior sims
running AI discussion turns) would queue its _do_project_switch behind
the auto-pruner's scan of tests/logs/ (154MB, 6519 files). The 4-worker
pool was saturated, so the switch would never run within 30s.

Fix: bump IO_POOL_MAX_WORKERS from 4 to 8. This gives the pool enough
capacity to run: 2 pruners + the project switch + 5 spare.

Also: add /api/io_pool_status endpoint + get_io_pool_status +
wait_io_pool_idle helpers (kept in api_hooks.py and api_hook_client.py
for the test_api_hook_client_io_pool.py tests, even though the test
itself no longer uses them - they remain useful for future tests that
want to assert pool state directly).

Also: add wait_for_warmup at the start of test_full_live_workflow to
ensure SDK modules are loaded before AI ops.

Test verification:
- test_full_live_workflow in isolation: 11.83s PASS
- test_full_live_workflow in batch (with 4 prior sims): 83.46s PASS
- 30/30 related unit tests PASS

"""Tests for ApiHookClient.get_io_pool_status and wait_io_pool_idle.
These methods allow tests sharing a live_gui session to wait for prior
tests' background io_pool work to drain before submitting new work.
ANTI-SIMPLIFICATION: Tests must verify the exact endpoint URL, the poll
contract (returns on idle=True, not on partial), and the timeout behavior.
