Update Taproot activation timeline: advance mainnet start date
Move Taproot signaling start date earlier to allow more time for miner preparation and coordination before the March 2027 timeout. Consensus changes: - Mainnet activation start: February 14, 2026 (was March 1, 2026) - Mainnet timeout: March 1, 2027 (unchanged) - Update nStartTime: 1771027200 (was 1772323200) - Applied to both mainnet and testnet deployments This extends the signaling window from 12 months to 12.5 months, providing miners additional time to upgrade and signal readiness for Taproot activation
