Function format_binary_int_to_string_with_scratch 

pub fn format_binary_int_to_string_with_scratch(
    value: i64,
    scratch: &mut ScratchBuffers,
) -> String

Format a binary integer into the caller-owned scratch buffer.

Why scratch?

Avoids hot-path allocations in codec routes that emit integers frequently (zoned/packed/binary). This writes into scratch and returns that buffer, so callers must reuse the same ScratchBuffers instance across a walk.

Contract

• No allocations on the hot path
• Returns the scratch-backed String (valid until next reuse/clear)
