…#14509) The server now sends a request to the client, to watch for `.oxfmtrc.json` or custom configurable `fmt.configPath` file content changes. The client will send a `workspace/didChangeWatchedFiles` notification to the server. The client can also send `workspace/didChangeConfiguration`, for now the server will restart both tools. This will be optimized by looking at which tool is responsible for the file in #14645

Pull Request Overview
This PR refactors the file watching system in the language server to provide more granular control over different tools (linter and formatter) by implementing separate watch patterns and registration/unregistration mechanisms.
- Moves from a single workspace watcher to tool-specific watchers with unique IDs
- Implements individual registration and unregistration of file watchers
- Adds new methods to generate watch patterns for linter and formatter tools

…14645) Now the worker is responsible to provide the dynamic registration with `Registration` and `Unregistration`. The worker will use the provided tools to detect the needed watcher changes. Before this PR, the server/Backend created the `Registration` struct for each worker, this was not great because we needed to register the watchers for the other tools too. Now every tool has its own `Registration.id` which can be unregistered. https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#client_registerCapability https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#client_unregisterCapability
