bun run build
bun run test

Expected Results

• bun run build: completes without errors

Validation note: Full bun run test and bun run build could not execute due to memory constraints (turbo run gets SIGKILL).

However: Phase 1 work (b23dd7b) already passed 67/67 tests. The stub removal (7f232a3) and package-lock.json cleanup (2c0eba0) are non-breaking changes — verified 0 imports of removed stubs before deletion.

Risk: LOW — deletions only, no source code changes.
