docs(readme + skills): document new schemas + Cursor/Windsurf/Cline MCP snippets

- README.md + zh-TW: add manual mcp.json snippet block for Cursor / Windsurf
  / Cline (the three hosts without scripted installer). Per-IDE config path
  table inside <details>.
- skill_sample/claude/ecp/SKILL.md: refresh NodeKind / RelType lists to
  cover schema additions on origin/main since the branch diverged —
  EnumVariant, PathLiteral, TransactionScope, Annotation, Struct/Enum/Trait
  /Impl/Namespace/Module/SchemaField/EventTopic node kinds + Decorates /
  OpensTxScope / UsesPathLiteral / MirrorsField / Publishes / Subscribes /
  EventTopicMirror / Overrides rel types.

+
+These hosts read an `mcp.json` (or equivalent) but the file location varies per IDE. Paste this server entry into the host's MCP config; the binary just needs to be on `$PATH`:
+
+```json
+{
+  "mcpServers": {
+    "ecp": {
+      "command": "ecp",
+      "args": ["admin", "mcp", "serve"]
+    }
+  }
+}
+```
+
+Per-host file:
+
+- **Cursor** → `~/.cursor/mcp.json` (global) or `<repo>/.cursor/mcp.json` (per-project)
+- **Windsurf** → `~/.codeium/windsurf/mcp_config.json`
+- **Cline** → VS Code settings → `cline.mcpServers` (object keyed the same way)
+
+After saving, restart the IDE; verify with `ecp admin mcp tools` matches what the host now lists.

+- **Cursor** → `~/.cursor/mcp.json`（global）或 `<repo>/.cursor/mcp.json`（per-project）
+- **Windsurf** → `~/.codeium/windsurf/mcp_config.json`
+- **Cline** → VS Code settings → `cline.mcpServers`（key 結構一樣）
+
+存檔後重啟 IDE，跑 `ecp admin mcp tools` 對照 host 那邊列出的工具集對得上即可。
