Merge remote changes: integrate MCP tools and resource refactor docs into framework

- Resolve directory rename conflict from old 03/06 dirs
- Move remote-added 资源加载重构方案.md into modules/frameworks/资源管理/
- Move remote-added 06_工具脚本/MCP工具 into modules/frameworks/编辑器工具/MCP工具/
- Keep Tools/CodexUnityMcp/ as MCP Server implementation
- Update README.md, modules/模块索引.md, and parent READMEs
- Add 文档关联 sections to new docs and fix old absolute paths

+# CrystalBattle Unity MCP
+
+This local MCP server exposes selected CrystalBattle Unity Editor commands to Codex.
+
+## Architecture
+
+- Codex connects to this MCP server over stdio.
+- The MCP server calls the Unity Editor bridge at `http://127.0.0.1:17777`.
+- The Unity Editor bridge executes Unity API work on the editor main thread.
+
+## Unity Setup
+
+Open `CrystalBattle_Client` in Unity. The bridge starts automatically after scripts compile.
+
+Manual controls are available from the bridge panel:
+
+```text
+Tools/Codex Unity MCP/Bridge Panel
+```
+
+The panel shows the current connection status, endpoint, listener thread state, pending command count, total request count, recent command, and cached log count. It also includes buttons to start, stop, restart, copy the endpoint, and print status to the Unity Console.
+
+## Install Dependencies
+
+From this directory:
+
+```powershell
+pnpm install
+```
+
+If `pnpm` is not on `PATH`, use the Codex bundled runtime:
+
+```powershell
+& "C:\Users\admin\.cache\codex-runtimes\codex-primary-runtime\dependencies\bin\pnpm.cmd" install
+```
+
+## Tools
+
+- `unity_health`
+- `unity_refresh_assets`
+- `unity_execute_menu_item`
+- `unity_get_console_logs`
+- `unity_generate_ui_prefab`
+- `unity_export_prefab_to_json`
+
+## Environment
+
+Optional:
+
+```text
+UNITY_MCP_BRIDGE_URL=http://127.0.0.1:17777
+```
+
+## Codex Config
+
+The workspace includes `.codex/config.toml` with a `crystalbattle-unity` MCP server entry.
+Restart Codex after dependency installation so the new MCP server is discovered.
