v0.3.38

Fixed

• Filled orders now heal missed position cache updates - After a terminal order update with non-zero fill quantity, the base OMS schedules a short delayed REST position resync. This repairs position cache misses when the exchange order callback arrives but the private position stream update is delayed or dropped. Overlapping fill-triggered resyncs are coalesced, and a fill that arrives while a resync is pending marks the task to run one more pass afterward.

Tests

• Added regression coverage for fill-triggered position resyncs, zero-fill terminal orders, and dirty resync coalescing.
• Verified with py -m pytest test\test_post_ack_terminal_reconcile.py test\exchange\test_cancel_success_reconcile_base.py test\test_ws_ack.py -q.
