Goal

Bring packages/Bus/Sources/Bus/WebviewBridge.swift up to the standard in .planning/code-commenting-guide.md. Load-bearing actor — Swift ↔ JS typed message bus, protocol version gating, harness parity.

Constraints

ONE atomic commit. No code behavior changes — comments + docstrings only.
18/18 boundary gates green.
Apply the guide's 5 comment shapes:
- 5-line opener at top of file (WHY this bridge exists, transport, protocol version contract)
- Type-level /// docstring with Overview + Topics + Threading + See Also
- Method-level docstrings on public + key private methods (send, receive, protocol negotiation)
- ASCII diagram of message flow (Swift → WKScriptMessageHandler → JS dispatcher, and the inbound path)
- "Before you edit" invariants block (bus-harness parity, no evaluateJavaScript outside the gated path, protocol version bump rules, single-writer HudState invariant)
- MARK dividers as a table of contents

Anti-patterns to remove

Plan-ID-only comments — rewrite WHY-first.
Stale references to closed Plan IDs or removed types.
Bare TODO: / FIXME: without issue link.

Follow the canonical pattern

Use the AppDelegate.swift P0 rewrite (#65) as the canonical applied pattern.
