feat: account management overhaul + 7 issue resolutions (#147)

- Add smart JSON export/import with schema validation and deduplication
- Add per-account proxy configurations (Issue #79)
- Add advanced account sorting engine (Issues #126 & #99)
- Add compact horizontal layout, AI credits, inline model visibility (Issues #145 & #134)
- Add desktop push notifications for low quota (Issue #53)
- Fix Arch Linux AUR process detection bug (Issue #117)
- Default theme set to Dark Mode (it's better)
- UI Polishing: Improved sort dropdown and symmetrical dialog layouts
- Dev Mode: Resolved port conflicts and single-instance locks
- Updated README and README.zh-CN with new features

-# CLI Feature - Pull Request Summary
-
-## What This PR Adds
-
-A complete **Command-Line Interface (CLI)** for Antigravity Manager with 18+ commands for power users.
-
-## Key Features
-
-- 📊 **Live Quota Monitoring** - Real-time tracking for Gemini & Claude models
-- 🔄 **Account Switching** - Seamless switching without manual token management  
-- ✅ **Token Validation** - Auto-refresh expired tokens
-- 🎯 **Smart Auto-Switch** - Automatically pick best account by quota
-- 🏷️ **Aliases** - Shortcut names for accounts (`work`, `personal`)
-- 💾 **Backup/Restore** - Export/import account configurations
-- 🎮 **Interactive Mode** - Keyboard-navigated menus for beginners
-- 🩺 **Diagnostics** - System health checks
-
-## Technical Highlights
-
-- **Zero Hardcoded Paths**: Intelligently discovers database and executable locations
-- **Cross-Platform Ready**: Uses environment variables and checks for Windows/Mac/Linux
-- **Secure**: Leverages existing DPAPI + AES-256-GCM encryption (same as GUI)
-- **Extensible**: Clean separation between core logic (`core.py`) and commands (`main.py`)
-
-## File Structure
-
-```
-cli/
-├── README.md           # Full documentation
-├── requirements.txt    # Python dependencies
-├── core.py            # Database, encryption, API logic
-├── main.py            # CLI commands and interactive UI
-└── proto_utils.py     # Protobuf encoding helpers
-```
-
-## Usage Examples
-
-```powershell
-# Interactive mode
-agm
-
-# Quick status
-agm status
-
-# Switch accounts
-agm switch work
-
-# Auto-switch to best account
-agm auto-switch --model claude --min-quota 50
-
-# Live monitoring
-agm watch
-```
-
-## Testing
-
-- ✅ Tested on Windows 10/11
-- ✅ No hardcoded paths (uses standard Windows env vars)
-- ✅ Works with both installed and development builds
-- ✅ Database encryption/decryption verified
-
-## Dependencies
-
-All Python dependencies are self-contained in `cli/requirements.txt`:
-- `typer` - CLI framework
-- `rich` - Beautiful terminal output
-- `questionary` - Interactive menus
-- `pywin32` - Windows DPAPI support
-- `cryptography` - AES-256-GCM encryption
-- `httpx` - Async HTTP client
-- `psutil` - Process management
-- `protobuf` - Google API protocol buffers
-
-## Platform Support
-
-- **Windows**: Full support (tested)
-- **macOS/Linux**: Partial support (no DPAPI, but core features work)
-
-## Breaking Changes
-
-None. This is a pure addition—no changes to existing GUI code.
-
-## Future Enhancements
-
-- OAuth flow for adding new accounts via CLI
-- TUI (Terminal UI) with live dashboard
-- Scheduled auto-refresh via Windows Task Scheduler
-- Config file for user preferences
-
-## Checklist
-
-- [x] Code follows existing style
-- [x] All commands have help text
-- [x] No hardcoded paths/credentials
-- [x] README with examples
-- [x] Dependencies in requirements.txt
-- [x] .gitignore updated for Python
-- [x] Works with fresh installs
