Adds a new UdpShredstream endpoint type that receives raw UDP shred packets, performs FEC recovery and deshredding to extract transactions directly from the validator's turbine layer — bypassing gRPC entirely. New files: - src/providers/udp_shredstream.rs: UDP socket listener with SO_REUSEPORT, multi-socket binding, and shred-to-transaction pipeline - src/deshred.rs: Shred decoding, FEC recovery via solana-ledger reed-solomon, and entry deserialization Changes to existing files: - config.rs: UdpShredstream variant in EndpointKind enum - providers/mod.rs: Wire up new provider in create_provider() - backend.rs: Map UdpShredstream kind to "shredstream" for backend compat, wrap bare socket addresses as udp:// URLs, skip URL parsing for UDP endpoints - main.rs: Add jemalloc allocator, drain signature forwarder before backend finalization, skip finalization when no cross-endpoint signatures collected - Cargo.toml: Add solana-ledger (jito fork), solana-sdk/perf/streamer/net-utils/ metrics, socket2, tikv-jemallocator, and release profile optimizations
