Add ability to @include Obsidian markdown files from Obsidian Vault

Fixes #4

Add ability to @include Obsidian markdown files from Obsidian Vault into chat messages.

* **Obsidian File Search and Integration:**
  * Add fuzzy searching to `searchObsidianFiles` function in `electron/ipc/obsidian.ts`.
  * Ensure `searchObsidianFiles` function returns top 10 results sorted by relevance.
  * Set up file watcher to invalidate cache when files change.
  * Ensure all values are strings and serializable.

* **Settings Modal:**
  * Add UI for selecting and displaying the Obsidian Vault path in `src/components/SettingsModal.vue`.
  * Add logic to handle folder selection and update the store.

* **Chat Message Integration:**
  * Integrate `useObsidianFiles` to fetch and embed notes into chat messages in `src/App.vue`.
  * Add inline preview with TailwindCSS for included notes.
  * Implement collapsible section for note preview using TailwindCSS.
  * Add toggle function for preview expansion.

* **Autocomplete List:**
  * Add `searchQuery` ref and `useDebounce` to debounce the search query in `src/composables/useObsidianFiles.ts`.
  * Implement `searchFiles` function to perform the search using `search-obsidian-files` IPC handler.
  * Watch `debouncedQuery` ref to update search results in real-time.
  * Display search results in the autocomplete list in `src/components/ObsidianMentionPopup.vue`.
  * Style the autocomplete list using TailwindCSS classes.

* **Store Schema:**
  * Add `obsidian-vault-path` to store schema in `electron/main/store.ts`.
