Snider f1ed1f0ac5 feat: WithService with v0.3.3 name discovery + IPC handler auto-registration
- WithService now calls factory, discovers service name from package path via
  reflect/runtime (last path segment, _test suffix stripped, lowercased), and
  calls RegisterService — which handles Startable/Stoppable/HandleIPCEvents
- If factory returns nil Value (self-registered), WithService returns OK without
  a second registration
- Add contract_test.go with _Good/_Bad tests covering all three code paths
- Fix core.go Cli() accessor: use ServiceFor[*Cli](c, "cli") (was cli.New())
- Fix pre-existing })) → }}) syntax errors in command_test, service_test, lock_test
- Fix pre-existing Options{...} → NewOptions(...) in core_test, data_test,
  drive_test, i18n_test (Options is a struct, not a slice)
