* docs: split Entity docs into sub-modules and fix Starlight CI

- Split monolithic entity.md into 4 focused sub-documents:
  - guide/entity/index.md - Overview and basic concepts
  - guide/entity/component-operations.md - Component API operations
  - guide/entity/entity-handle.md - EntityHandle system for safe references
  - guide/entity/lifecycle.md - Lifecycle and persistence management

- Created bilingual versions (Chinese and English)

- Updated sidebar configuration in astro.config.mjs

- Fixed CI workflow for Starlight migration:
  - Updated docs.yml to upload from docs/dist instead of .vitepress/dist
  - Updated package.json scripts to use pnpm filter for docs
  - Added docs directory to pnpm-workspace.yaml
  - Renamed docs package to @esengine/docs

- Documented missing Entity APIs:
  - createComponent() method
  - addComponents() batch method
  - getComponentByType() with inheritance support
  - markDirty() for change detection

* docs: split Network docs and fix API errors

- Split network module into focused sub-documents:
  - modules/network/index.md - Overview and quick start
  - modules/network/client.md - Client-side usage
  - modules/network/server.md - Server-side GameServer/Room
  - modules/network/sync.md - Interpolation and prediction
  - modules/network/api.md - Complete API reference

  - localClientId → clientId
  - ENetworkState enum values (strings → numbers)
  - connect() method signature
  - Removed non-existent localPlayerId property
  - Fixed onConnected callback signature
