refactor(codegen): remove all MCP functionality from codegen

Remove MCP (Model Context Protocol) tool generation, mcp.json file
generation, and related config/types/tests. MCP was generating static
JSON tool definition files that weren't providing value.

Removed:
- getCliMcpTools(), getMultiTargetCliMcpTools() from cli/docs-generator.ts
- getOrmMcpTools() from orm/docs-generator.ts
- getHooksMcpTools() from hooks-docs-generator.ts
- generateCombinedMcpConfig() from target-docs-generator.ts
- McpTool interface from docs-utils.ts
- mcp option from DocsConfig interface and resolveDocsConfig()
- All MCP imports and if(docsConfig.mcp) blocks from generate.ts
- 5 MCP test cases and 2 snapshots from cli-generator.test.ts
- McpTool re-exports from cli/index.ts barrel
