Attempt to fix zod import for ipc module

Configure vitest to inline zod dependency and update zod wrapper to ES module format.

Note: ipc.test.ts still fails with 'Cannot read properties of undefined (reading object)'.
This appears to be a vitest/zod integration issue that needs further investigation.

Current test status:
- 5 test suites passing (187 tests)
- 1 test suite failing (ipc.test.ts - zod import issue)
