This commit restructures the file search settings. The previously individual settings for file search method, regex search backend, match search backend, and ripgrep path have been grouped into a new filesSearchSettings object.
- Introduces a new match_search_files tool for fuzzy/keyword search, integrating with Obsidian's core search plugin and updating Omnisearch integration for improved file search capabilities.
- Adds settings for selecting search backends (core plugin, Omnisearch, ripgrep) for both regex and match searches.
- Updates language files, prompts, and types to support the new functionality.
- Restructures search-related files for better organization.
