fix: use 0.001/0.999 bounds — 1e-6 formats as 0.0000 in :.4f stdout which validator reads as 0.0

fix: eliminate all exact 0.0/1.0 paths, update reward_range in yaml and api to strict (0,1) bounds

fix: resolve full task IDs from openenv.yaml, add /tasks endpoint, harden score range to (0,1) exclusive

fix: clamp task scores to strictly open (0, 1) interval for Phase 2 validator
