GitHubandClaude Opus 4.8 46298e68d7 fix(backtest): max drawdown now correctly measures peak-to-trough percentage ...

Previous formula was: max(absolute_drawdown) / initial_capital, which
exceeds 100% when the portfolio grows then drops (e.g. from 600k to 300k
on a 100k initial = 300% drawdown, which is nonsensical).

Fixed to use drawdown_pct (drawdown / peak) which is always in [0, 1].
This correctly measures the maximum percentage drop from the highest
equity peak, matching the standard financial definition.

Also added regression test: test_max_drawdown_never_exceeds_100_pct.
