[WIP] Add file search plugin to Wox

Implemented a new file search feature in the Wox launcher. This includes creating new structures for search patterns and search results, as well as an interface for a searcher in `searcher.go`, and macOS-specific implementation in `searcher_darwin.go`. It also includes necessary updates in `main.go` and `plugin.go` for plugin registration and handling search queries.
