Detailed Description

Timer field union for openlcb_msg_t.

Shares one byte between two mutually exclusive uses:

• assembly_ticks: full 8-bit tick snapshot for multi-frame assembly timeout (used by CAN RX message handler and BufferList timeout).
• datagram: split into a 5-bit tick snapshot and a 3-bit retry counter for datagram rejected/resend logic.

Only one interpretation is active at a time depending on the message lifecycle stage.
