Map NodeTrace to canonical runtime events

[HomenShum]

Outcome

Restacks NodeTrace's truthful NodeKit L1/L2 brownfield map directly on the merged P0 contract.

• keeps NodeTrace a portable trace UI and SQLite package, not another agent runtime
• declares consumption of nodeagent.event/v1, the trace-workpaper contract, and ProofLoop certification
• documents the missing canonical event translator and receipt wrapper instead of claiming them
• preserves the existing stronger P0 lifecycle commands and deterministic no-key path

Proof

• NodeKit repository conformance: pass against the coordinated registry
• happy path: pass
• CLI, package, and MCP smoke: pass
• TypeScript and Vite production build: pass
• git diff --check: pass

Dependency status

The branch's product verification and security checks pass. Hosted node-platform / conformance fetches node-platform/main and is expected to remain red until the event-consumer ownership in node-platform #4 lands.

Boundary

This maps ownership and dependencies only. It does not implement the canonical event translator, change the SQLite schema, publish npm, or deploy anything.

Supersedes #2, whose pre-P0 base became conflicting after P0 merged.
