Subject: [PATCH] fix(weights): persist label weights into <label>_weight
 column instead of rescaling target
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Removes statistically incorrect target rescaling (label = direction × weight). Persists raw direction labels and a separate <label>_weight column for downstream sample_weight composition. Validated locally with pytest (evidence: .omo/evidence/task-6-{red,green}.txt).
