Initial commit: ClaudeTeX - LaTeX editor with Overleaf sync

Features:
- Electron + React + TypeScript app with Cosmic Latte theme
- CodeMirror 6 editor with LaTeX syntax highlighting
- PDF preview with pdf.js, zoom controls, SyncTeX double-click jump
- File tree with context menu (new/rename/delete/reveal)
- Overleaf Git clone with token auth + macOS Keychain storage
- Git pull/push sync for Overleaf projects
- Embedded terminal (xterm.js + node-pty) with Claude CLI integration
- LaTeX compilation via latexmk with auto package install detection
- Structured compile log (errors/warnings) with click-to-navigate
- Main document setting (auto-detect or right-click to set)
- Custom modal system (input/confirm/alert)
- Resizable panel layout (file tree | editor | PDF + terminal)
