Agave release tightens validator failure handling

Anza released Agave 4.3.0 as a stable version for Solana's testnet, devnet and mainnet beta. The update changes how validators respond to several operational failures and adds controls for configuring rewards and revenue collection.

When Bigtable storage or upload is enabled, a failed connection now causes a fatal error rather than allowing the process to continue after logging the problem. Loading a snapshot with invalid vote accounts also produces an error instead of silently dropping those accounts. Banking trace recording is disabled by default.

The release adds command-line support for setting commission in basis points and configuring collectors for inflation rewards and block revenue. Its stricter failure handling makes incomplete storage or invalid snapshot state more visible to operators, while requiring deployment procedures to account for conditions that previously allowed startup to continue.
