Detailed Description

Layer 6 (Presentation) - zero-heap CBOR (RFC 8949) encoder.

A streaming encoder that writes directly into a caller-provided buffer (no heap), the binary counterpart to the JSON writer. Emit definite-length arrays and maps by writing the header (cbor_array / cbor_map with the item count) then that many items (twice that for a map: key, value, key, value, ...).

Overflow is tracked, not crashed on: writes past the buffer set the overflow flag and stop, while cbor_len() keeps counting the bytes the full payload would need, so a caller can size the buffer and check cbor_ok().
