test(e2e): complete the embedding.ts mock export surface for the cycle-sync import path

The wave's sync changes make the cycle sync phase lazily import
commands/sync.ts, whose static embedding.ts imports must all resolve
against the test's module mock (a missing name is a load-time
SyntaxError). Stubs mirror the real pure functions.
