Add RESTful routing with resources function

[tamurashingo]

Summary

• Add action-based routing that dispatches to named controller methods (index, show, new, etc.) using :action and :method in route definitions
• Extend path-controller to match routes by both path and HTTP method
• Add resources function to generate 7 standard RESTful routes in a single call
• Support :only / :except options to selectively include or exclude actions
• Maintain full backward compatibility with existing do-get / do-post dispatch
• Update controller documentation (English and Japanese)

Usage

;; Generate all 7 standard RESTful routes
(setf clails/environment:*routing-tables*
  `(,@(resources "todos" "myapp/controllers/todo-controller:<todo-controller>")))

;; Generate only specific actions
(resources "todos" "controller" :only '(:index :show))

;; Exclude specific actions
(resources "todos" "controller" :except '(:destroy))

Changed files

• src/controller/base-controller.lisp — Add action slot, HTTP method-aware path-controller, resources function
• src/middleware/clails-middleware.lisp — Add call-action function and action dispatch logic
• test/controller/base-controller.lisp — Add routing and resources tests
• document/controller.md / document/controller_ja.md — Add RESTful routing documentation

Test plan

• All 64 existing tests pass
• resources generates 7 routes in correct order
• /todos/new is not matched as :id parameter
• :only / :except options filter actions correctly
• Each HTTP method × path combination routes to the correct action
• Routes without :action continue to dispatch to do-get etc. (backward compatibility)
