Cathedral Fixes Incentive Issues, Launches v3

SN39 experienced validator weight-setting failures preventing miner rewards. A validator upgrade was deployed to stabilize incentives. Version 3, a major upgrade, is shipping today. Two new code-oriented job families—bug reproduction and test generation—are coming post-release, requiring miners to write executable tests and regression suites for real GitHub repositories.

• •Validator upgrade deployed to fix incentive distribution failures
• •Major v3 subnet upgrade launching today
• •Bug reproduction jobs: write tests from GitHub issues
• •Test generation jobs: improve coverage on real codebases
