Summary

New() returns Result, accepts CoreOption functionals
WithService(factory func(*Core) Result) — service factory receives Core during construction
WithOptions(Options) — key-value configuration
WithServiceLock() — immutable conclave after construction

Restores the v0.3.3 service registration contract adapted for the dev branch DTO pattern. Services registered in New() form the application conclave with shared IPC access. Each Core instance has its own bus scope.

Test plan

go build ./... passes
go test ./... passes (all 24 files updated)
New tests: TestNew_WithService_Good, TestNew_WithServiceLock_Good

fix: address Codex review findings on PR #28 b5dcdbb216

- WithOptions copies the Options slice (constructor isolation regression)
- WithService auto-discovers service name from package path via reflect
- WithService auto-registers HandleIPCEvents if present (v0.3.3 parity)
- Add test for failing option short-circuit in New()

fix: prevent double IPC registration + empty service placeholder 3a9ac82275

- HandleIPCEvents only auto-registered for services the factory didn't
  register itself (prevents double handler registration)
- Auto-discovery only creates Service{} placeholder when factory didn't
  call c.Service() — factories that register themselves keep full lifecycle

Addresses Codex review findings 1 and 2 from third pass.

fix: move HandleIPCEvents discovery to New() post-construction 98d078130e

WithService is now a simple factory call — no reflect, no auto-registration.
New() calls discoverHandlers() after all opts run, scanning Config for
service instances that implement HandleIPCEvents.

This eliminates both double-registration and empty-placeholder issues:
- Factories wire their own lifecycle via c.Service()
- HandleIPCEvents discovered once, after all services are registered
- No tension between factory-registered and auto-discovered paths

feat: RegisterService with instance storage + interface discovery 7ee897d12b

Restores v0.3.3 service manager capabilities:
- RegisterService(name, instance) stores the raw instance
- Auto-discovers Startable/Stoppable interfaces → wires lifecycle
- Auto-discovers HandleIPCEvents → wires to IPC bus
- ServiceFor[T](c, name) for typed instance retrieval
- Service DTO gains Instance field for instance tracking

WithService is a simple factory call — no reflect, no magic.
discoverHandlers removed — RegisterService handles it inline.
No double-registration: IPC wired once at registration time.

feat: Options struct + Result methods + WithOption convenience d5e388fbb2

Options is now a proper struct with New(), Set(), Get(), typed accessors.
Result gains New(), Result(), Get() methods on the struct.
WithOption("key", value) convenience for core.New().

options_test.go: 22 tests passing against the new contract.
Other test files mechanically updated for compilation.

feat: App struct with New(Options) + Find() as method d8fb18a663

App.New() creates from Options. App.Find() locates programs on PATH.
Both are struct methods — no package-level functions.

feat: WithService with v0.3.3 name discovery + IPC handler auto-registration f1ed1f0ac5

- 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)

feat: WithService with v0.3.3 name discovery + IPC handler auto-registration 0342089b0e

WithService now: calls factory, discovers service name from instance's
package path via reflect.TypeOf, discovers HandleIPCEvents method,
calls RegisterService. If factory returns nil Value, assumes self-registered.

Also fixes: Cli() accessor uses ServiceFor, test files updated for Options struct.
