Proposal #81: Kimi cPoC Restitution (epochs 306-309)

Distribute restitution for Kimi operators affected by cPoC validation failure in epochs 306-309. The Kimi validation path failed starting in e306 causing confirmation weight suppression for Kimi operators while non-Kimi operators ran normally. Failure worsened in e307 and carried into the e309 bootstrap attempt. Total: 175082.07 GONKA to 19 addresses, vested over 170 days (160 epochs).
