Originally tracked as an inline TODO in island_model/qsh_parser.py. OwnOrders is the user's own order log — required to compute realistic slippage in the backtester (vs. the current 'no self-trade' assumption).
Acceptance criteria:
- Parse OwnOrders stream header.
- Expose own-order lifecycle (place, modify, cancel).
- Wire into portfolio_backtester so backtests can model slippage from observed own-order queue position.
