Add non-standard `sendBundle` RPC endpoint for Jito bundles imitation, allowing clients to submit multiple transactions that are executed sequentially. This is useful for testing applications that use Jito bundles. Key features: - Transactions are processed sequentially in order - Forces skip_preflight to match Jito Block Engine behavior - Returns bundle ID as SHA-256 hash of comma-separated signatures - If any transaction fails, the entire bundle is rejected Note: This is not a 100% bundles implementation as they are not atomic all-or-nothing like real Jito bundles.

There was a problem hiding this comment.
This is awesome! Sorry for the delay on review. I pushed a few small changes to this branch:
- maximum of 5 txs per bundle (matching JITO)
- clarified some comments indicating this isn't atomic. making the transactions atomic should be doable without a crazy amount of work, but I didn't want to further hold up this PR, so I made #594

This is not a 100% bundles implementation as they are not atomic all-or-nothing like real Jito bundles. But it's useful for testing apps that want to verify their Jito integration works.
