chore(deps): add @pascal-app/lingo to the lockfile; note duplicated helper

Records @pascal-app/lingo@^0.1.0 in bun.lock (added to @pascal-app/editor and
@pascal-app/mcp), so `bun install --frozen-lockfile` in CI resolves it. Also
documents that measurement.ts is intentionally duplicated with the AI-chat copy
across the submodule boundary and must be kept in sync.
