Gittensor overhauls scoring, adds six repos

Gittensor shipped major scoring changes moving from global to per-repository eligibility gates and emission tuning. Six new community repos added to the master list. Maintainers can now claim a configurable emission carve-out before PR/issue payouts split. Miners contributing across multiple repos will see scoring shifts; team recommends reviewing each repo's configuration.

• •Six repos added: product-data-extractor, ragflow, awesome-claude, vouch, touchpilot, sure.
• •Per-repo eligibility: minimum PRs 5→3, issues 7→3; open PR/issue penalties now repo-scoped.
• •Maintainer emission carve-out: repos can reserve fraction of emissions for registered maintainers.
• •PR scoring lookback window shortened from 35 to 30 days; multiple bug fixes applied.
