🤖 Consolidate duplicated test infrastructure

After the SSH runtime commit (#178), testing infrastructure had significant
duplication across helper modules and inline functions.

Changes:
- Consolidated shared utilities into tests/ipcMain/helpers.ts
  - Added extractTextFromEvents(), sendMessageAndWait(), createWorkspaceWithInit()
  - Centralized test constants (INIT_HOOK_WAIT_MS, SSH_INIT_WAIT_MS, HAIKU_MODEL, etc.)
- Deleted tests/ipcMain/test-helpers/runtimeTestHelpers.ts (149 lines)
- Removed inline helper duplicates from test files
  - runtimeFileEditing.test.ts: -120 lines
  - removeWorkspace.test.ts: -39 lines
  - renameWorkspace.test.ts: -45 lines
  - runtimeExecuteBash.test.ts: simplified imports

Result: 240 net lines removed, improved consistency across integration tests.

All tests use consistent patterns from single source of truth.
