fix: enforce absolute determinism in inference agent by relying on observation only

feat: upgrade baseline agent to handle constraints intelligently

feat: upgrade grading logic to Phase 2: constraint-aware and partial scoring

feat: implement dynamic constraint system with stochastic generation and UI visualization

feat: upgrade environment realism with randomization and improved scoring

fix: clamp extreme boundaries dynamically protecting against hard 0 or 1 edge constraints per phase 2 validator math

feat: ambiguity resolution environment v1.0 - OpenEnv Hackathon
