refactor(explorer): improve file history state management

Adjusts the logic governing when file history views are refreshed or displayed. This ensures that selecting a file via the explorer correctly hides any active file history view, and prevents unnecessary refreshes of history data if the view is already collapsed or if the repository path is not yet set.

- Added explicit function to reset file history state
- Prevents automatic display of file history upon file selection
- Refines conditions for refreshing file history during repo updates

-## Funktionen
+# Gitty
 
-- Repository per lokalem Pfad öffnen
-- aktuellen Branch, Upstream, Ahead/Behind und Arbeitsbaumstatus anzeigen
-- Branches auflisten und auschecken
-- Branches in den aktuellen Branch mergen
-- Commit-History mit geänderten Dateien anzeigen
-- Explorer-Ansicht mit Ordnerbaum sowie getrackten und ungetrackten Dateien
-- Datei- und Ordner-History direkt aus dem Explorer anzeigen
-- einzelne Dateien stagen, unstagen und wiederherstellen
-- einzelne Dateien oder ganze Ordner aus einem History-Commit wiederherstellen
-- aktuellen Branch auf einen ausgewählten Commit zurücksetzen
-- Commit mit Message erstellen
-- Pull mit Fast-Forward-Strategie
-- Push auf den konfigurierten Upstream
+**A lightweight, modern Git client built with Tauri.**
 
-## Entwicklung
+Fast, simple, and designed for developers who want a clean Git experience without unnecessary complexity.
 
-```powershell
-npm install
-npm run tauri:dev
-```
+</div>
 
-Frontend allein:
+---
 
-```powershell
-npm run dev
-```
+## ✨ Features
 
-Checks:
+- 🚀 Fast native performance
+- 🌿 Branch management
+- 📝 Commit history
+- 🔄 Pull, Push & Fetch
+- 🔀 Merge & Rebase
+- 📦 Repository management
+- 🎨 Modern and intuitive UI
 
-```powershell
-npm run check
-npm run build
-cd src-tauri
-cargo check
-```
+---
 
-## Hinweis
+## 📸 Preview
 
-Die App nutzt das lokal installierte `git` CLI. Ein Repository muss daher bereits auf der Maschine vorhanden sein, und Push/Pull verwenden die Credentials, die Git lokal kennt.
+> Screenshots coming soon.
+
+---
+
+## 🛠️ Built With
+
+- **Tauri**
+- **Rust**
+- **Svelte**
+

+
+## 🚧 Status
+
+Gitty is currently under active development.
+
+Contributions, feedback and feature requests are always welcome!
