T1.4.1 — Add rustdoc on MiniHeaderV2 / MiniFrameContextV2 public items

Status: Pending Review Agent: Kimi Code CLI Started: 2026-05-11T07:26Z Completed: 2026-05-11T07:27Z Commit: see git log PRD: ../PRD-wire-format-v2.md

What I changed

• crates/wzp-proto/src/packet.rs:641-645 — added /// doc comments to all 3 fields of MiniHeaderV2 (seq_delta, timestamp_delta_ms, payload_len)
• crates/wzp-proto/src/packet.rs:648 — added /// doc on WIRE_SIZE
• crates/wzp-proto/src/packet.rs:650 — added /// doc on write_to
• crates/wzp-proto/src/packet.rs:656 — added /// doc on read_from
• crates/wzp-proto/src/packet.rs:705 — added /// doc on MiniFrameContextV2::update
• crates/wzp-proto/src/packet.rs:709 — added /// doc on MiniFrameContextV2::expand

Why these choices

Follow-up from T1.4 review: coding standard #9 requires /// on all public items. Added concise one-line docs matching the task spec examples.

Deviations from the task spec

None.
