Module serde 

Compact binary serialization for Interval Tree Clock stamps.

Wire format (v1)

version:            u8        (currently 1)
id_bits_len:        varint    (number of meaningful bits)
id_bits:            bytes     (packed MSB-first)
event_bits_len:     varint    (number of meaningful bits)
event_bits:         bytes     (packed MSB-first)
event_values_len:   varint    (number of bytes)
event_values:       bytes     (varint-encoded node values)

Id encoding (preorder):

• 0 bit = leaf, followed by 1 bit for value (0 => Id::Zero, 1 => Id::One)
• 1 bit = branch, followed by left subtree then right subtree

Event encoding (preorder):

• node kind bit: 0 leaf / 1 branch
• node value/base: unsigned varint
• branch then continues with left subtree, then right subtree

This split representation keeps branch/leaf structure bit-packed while preserving compact integer encoding for counters.
