## Prompt

The human reported silent IB roaming and requested an immediate fix
after investigation found the custom nanosecond timestamps incompatible
with ib_async's datetime-based idle timeout arithmetic.

## Response summary

Override NonShittyWrapper._setTimer to accept integer nanosecond packet
timestamps while delegating datetime/sentinel states upstream. Keep the
packet timestamp unchanged on integer-path expiry, clear the timer
before timeoutEvent emission, and preserve reentrant listener rearming.
No default heartbeat, reconnect, or idle-timeout arming is introduced.

## Files changed

- piker/brokers/ib/api.py: compatible idle timer arithmetic/lifecycle.
- tests/test_ib_wrapper_timeout.py: three deterministic offline tests.

## Verification

Nineteen tests passed: new wrapper-timeout regressions and existing IB
history/method-proxy tests. Restoring the upstream method in memory
reproduced datetime-minus-int TypeError. No IB service or live network
was contacted; installed dependencies and original user work were
unchanged. The isolated worktree index remains unchanged.

## Human contributions

The human supplied rfkill/suspend/roam evidence, requested a session
health design, and prioritized fixing the discovered timestamp mismatch.
The implementation deliberately preserves their nanosecond feed schema.
Acceptance and live validation remain pending.
