kernel: Add recent assumeutxo snapshot info
What changed, and why it matters
This commit simply adds new pre-calculated snapshot data for a Bitcoin Core feature called 'assumeutxo.' It does not change any security logic, fix a bug, or introduce a vulnerability. It is a routine data update.
No security action needed; treat as routine data update.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch appends new Assumeutxo snapshot entries (height, serialized hash, chain transaction count, block hash) for mainnet, testnet3, testnet4, and signet. These constants are used by the assumeutxo feature to allow faster initial sync from a trusted UTXO set snapshot. No code behavior is altered beyond recognizing these additional snapshots.
