Add aoa-techniques stats port

[8Dionysus]

Summary

• add the owner-local stats port for published promotion-readiness coverage
• integrate the stats validator into canonical source and release lanes
• centralize executable command guidance in lane owners and appropriate AGENTS surfaces
• refresh the repository-local KAG family

Evidence

• manual positive census: 107 of 107 published technique records pass local blockers
• manual negative trial rejects the 98 canonical-only numerator
• source-fast and full release gates pass with pinned aoa-kag, aoa-stats, and abyss-machine dependencies
• 602 unittest cases across 15 homes and 35 part-local pytest cases pass
• generated projections and repository-local KAG validate cleanly
