v0.2.0

• Trust Scores: Introduced numeric data quality evaluation (trust_score) on the KestEntry model.
• Dynamic Trust Propagators: Added trust_score_updater to the @kest_verified decorator, allowing node-specific synthesis of parent trust scores (e.g. upgrades/degrades via custom lambda functions). Defaults to propagating the lowest (minimum) trust score from the parents.
• Policy Enforcement: Integrated trust_score directly into the OPA payload context to allow dynamic runtime blocking on minimum trust thresholds.
• Trust Origination: Added trust_score parameter to the originate helper function to jump-start external data with specific trust baselines.
