feat: add i18n translation examples to app-todo and app-crm

[Copilot]

No i18n examples existed despite comprehensive TranslationBundleSchema support in the spec. Adds working translation bundles to both example apps.

app-todo (3 locales: en, zh-CN, ja-JP)

• Task object: all 19 field labels, select options (status/priority/tags), help text
• App label, 19 UI messages, 2 validation messages

app-crm (4 locales: en, zh-CN, ja-JP, es-ES)

• 4 core objects (Account, Contact, Lead, Opportunity) with full field/option coverage
• App & nav translations, 21 UI messages, 3 validation messages

Wiring pattern

Both follow the existing barrel-import convention:

import * as translations from './src/translations';

export default defineStack({
  // ...
  translations: Object.values(translations),
});

Each *.translation.ts exports a typed TranslationBundle covering objects, apps, messages, and validationMessages:

import type { TranslationBundle } from '@objectstack/spec/system';

export const TodoTranslations: TranslationBundle = {
  en:      { objects: { task: { label: 'Task', fields: { ... } } }, messages: { ... } },
  'zh-CN': { objects: { task: { label: '任务', fields: { ... } } }, messages: { ... } },
  'ja-JP': { objects: { task: { label: 'タスク', fields: { ... } } }, messages: { ... } },
};

README

• Added I18n row to System Protocol coverage map
• Updated directory structures and feature lists for both examples
• Added translations/ to standard file structure convention
