Introduce SNS (朋友圈) and batch image tooling and enhance the GUI export workflow. Added new scripts: decrypt_sns.py (decrypt WeChat SNS cache) and batch_decrypt_images.py (bulk .dat image decrypt). Update build scripts and PyInstaller spec to include the new files. app_gui.py: add contact discovery, contact selection/export options dialog, new buttons (find image key, SNS), orchestrate combined export/voice/SNS tasks via subprocesses and env flags, and auto-run export after decryption. config.py: add output_base_dir, auto-detect WeChat Files path, and expose msgattach/xwechat cache dirs. export_messages.py: switch to output_base_dir, add image resource lookup and .dat locating/decryption helpers, and support environment-driven contact/format/image filters. Misc: update build.bat and packaging datas to include the new modules.

Introduce a tkinter GUI and tooling to produce a single executable and export/convert message data. Adds app_gui.py (GUI launcher that runs decrypt/export/voice subtasks), export_messages.py (export messages to CSV/HTML/JSON), voice_to_mp3.py (extract SILK_V3 voice blobs and convert to MP3 via pilk + ffmpeg), WeChatDecrypt.spec and build.bat (PyInstaller spec and convenience build script), and EXE_USAGE.md (usage for the standalone exe). Update config.py to detect the application base directory when packaged, update README.md to document the GUI and packaging flow, and add pilk/pyinstaller to requirements.txt. Also expand .gitignore with common IDE/build/temp patterns and add output/data directories to ignore. These changes enable one-file packaging and provide end-user tools for decrypting, exporting and converting audio.
