Detailed Description

Static encode helpers for the generated encode bodies.

Each takes the write cursor by value and returns it advanced, so outlined calls at -Os chain through the return register instead of a stack slot. Helpers without a _force suffix skip fields holding the proto3 default.

Encode a 48-bit MAC address (stored in a uint64) as varint.

Real MAC addresses occupy the full 48 bits (OUI in upper 24), so the fast path – any non-zero bit in the top 6 of 48 – emits exactly 7 bytes with no per-byte branch. Falls back to the general loop otherwise. Caller must guarantee value fits in 48 bits (checked in debug builds).
