Root Reborn (PR

Root dividends stop cashing out to TAO and are re-bought into a validator-curated basket of subnets that stakers redeem to TAO on demand. Live on mainnet since subtensor spec_version 441 (PR #2968, merged in release v441).

• TL;DR — The short version — what changes and what you actually do.
• Full explainer — The complete walkthrough of baskets, claiming, and mechanics.
