Codecov flagged a single uncovered line in crates/wickra-data/src/resample.rs:
line 46, the `self.low = c.low;` assignment inside RolledBar::absorb.
None of the existing resampler tests fed a follow-up candle with a strictly
lower low than the first candle in the bucket, so the `c.low < self.low`
branch never fired. Coverage stayed at 122/123.
Add a small dedicated test that pushes a 10.0-low candle into bucket 0, then
a 8.0-low candle into the same bucket, and asserts the rolled bar's low
reflects the dip. Resample file is now at 123/123 lines, no behavioural change.
