Rectangle / horizontal-range breakout

Thesis (rejected): A true rectangle — ≥3 touches at horizontal support AND ≥3 touches at horizontal resistance over the prior 60 days, range height ≤ 20 % — should add information beyond what coil_breakout (no touch-count requirement) already finds.

Code: research/rectangle_breakout.py Report: research/rectangle_breakout_report.json (n=5,132)

Verdict: Reject. The multi-touch requirement does not improve on coil_breakout; if anything, the longer 60-day flat structure selects names that are less primed (older bases that have already been picked over) than the 10-day coil cohort.
