feat: add like and favorite functionality for feeds (#207)

* feat: add like and favorite functionality for feeds

- Implemented handleLikeFeed and handleFavoriteFeed methods in mcp_handlers.go to manage liking and favoriting feeds.
- Added LikeFavoriteArgs struct in mcp_server.go for handling parameters.
- Registered new MCP tools for liking and favoriting feeds in registerTools function.
- Introduced LikeFeed and FavoriteFeed methods in XiaohongshuService to interact with the respective actions.
- Created LikeFavoriteAction in a new file to encapsulate the logic for liking and favoriting feeds on the Xiaohongshu platform.

* "Fix-build-errors"

* refactor: streamline like and favorite actions in LikeFavoriteAction

- Introduced a generic method `performInteractAction` to handle both liking and favoriting feeds, reducing code duplication.
- Updated logging to reflect the action type being performed (like or favorite).
- Enhanced state verification after interaction to ensure accurate feedback on success or failure.
- Removed the `clickLastMatch` function, simplifying the interaction logic.

* "Add-unlike-and-unfavorite-functionality"

* "Refactor-performInteractAction-function"

* "Refactor-split-LikeFavoriteAction-into-separate-actions"
