Prop 64: Save the network money: right-size x/mint inflation (goal_bonded 67%→60%, inflation_max 10%→7%) so Regen can refocus on revenue

For the whole network's benefit. Regen is currently minting REGEN at the maximum rate (inflation_max, 10%) with no path down: goal_bonded (67%) chases an actual bonded ratio (~60.6%) that the stock Cosmos SDK mint formula structurally cannot let it reach, so inflation stays pinned at the ceiling and the network dilutes every holder at the maximum rate for security it is not actually getting. This is a standard x/mint MsgUpdateParams — no new code, no chain upgrade, effective the moment it passes — setting goal_bonded 0.67→0.60 (matching reality so inflation can finally ease off the ceiling) and inflation_max 0.10→0.07 (slowing dilution while the bonded pool is this thin). It saves the network real money and protects REGEN's value, so the community and Foundation can put their energy into actual revenue — ecocredit issuance and agentic ecological work (EWP) — instead of fighting structural dilution. It continues a body of contributor work (brawlaphant): community-call participation, the ERC-1155 credit-wrapping and Hybrid Ecological Bonds designs, and the Economic Reboot framework, all aimed at making Regen economically self-sustaining.
