Adds a full tick-level backtest path that operates on raw tick arrays
(ltp, bid, ask, per-tick buy/sell qty deltas, oi) plus caller-computed
entry/exit signal bool arrays. Entry fills at ask+slippage; stop/target
checked against ltp on every tick; max-hold-seconds time exit; cooldown
between entries. Produces identical BacktestMetrics as run_single_backtest
via the new compute_backtest_metrics free fn.
5 Rust unit tests: target-hit, stop-hit, time-exit, multi-trade-with-cooldown,
empty-ticks edge case — all pass (138 total, 0 failed).
