Buffer Management
UTXOPersisterBufferSize is parsed using bytesize.Parse()- Falls back to 4KB (4096 bytes) if parsing fails
- Used for buffered I/O operations when reading/writing UTXO files
I/O Operations
UTXOPersisterDirect controls direct I/O behavior- Affects how buffer operations are performed
