release: 0.1.2

Ships parallel grid-search optimization, HTML reports, and the O(1) data
window that landed since 0.1.1.

Also tracks the sample EURUSD hourly CSV. The examples and the README's
157x benchmark all read data/EURUSD_1H.csv, which was gitignored, so none
of them ran on a fresh clone. `data/` becomes `data/*` plus a negation
because git cannot re-include a file whose parent directory is excluded.

 # Changelog
 
-## [Unreleased]
+## [0.1.2] - 2026-08-13
 
 ### Added
 - `Backtest.optimize()` — parallel grid search over a vectorised signal function.
@@ -9,10 +9,15 @@
 - `strategy_class` is now optional, so `Backtest(df, cash=...)` works for optimization
 - Standalone HTML reports (`Backtest.plot()`) and `examples/html_report.py`
 - Three-way speed benchmark against backtesting.py (`examples/benchmark.py`)
+- Sample EURUSD hourly data is now in the repo, so the examples run on a fresh clone
 
 ### Fixed
 - Data access inside `next()` is O(1) per bar instead of O(n) — ~2.6x faster
 
+### Changed
+- `numpy` is now a direct dependency (it was already pulled in by pandas)
+- CI runs `cargo clippy -- -D warnings` in place of `cargo check`
