refactor: enforce device labels, unify screenshot, remove deprecated commands, session-id-less design
- Device labels: lowercase, no whitespace, only a-z 0-9 - _ (enforced at config time)
- Session IDs removed: device label is the sole identifier
- Routes changed: /sessions/:id → /devices/:label
- Removed commands: click, type, find-window, wait-for-window, label, old version, server-version
- Renamed: status → version (compares relay/remote.py/client commits)
- Unified screenshot: takes 'screen' or a window label as argument
- Windows listed with human-readable labels (same format as device labels)
- Single instance enforcement via PID lock file
- Removed input.rs (click/type functionality)
- All docs and code in English
- Protocol: Hello.label is now required (String, not Option<String>)
- Client auto-migrates invalid labels on startup

# helios-client
Windows client for helios-remote. Connects to the relay server via WebSocket and executes commands.
## Features
- Full-screen and per-window screenshots
- Shell command execution (persistent PowerShell session)
- Window management (list, focus, maximize, minimize)
- File upload/download
- Clipboard get/set
- Program launch (fire-and-forget)
- User prompts (MessageBox)
- Single instance enforcement (PID lock file)
## Configuration
On first run, the client prompts for:
- **Relay URL** (default: `wss://remote.agent-helios.me/ws`)
- **API Key**
- **Device label** — must be lowercase, no whitespace, only `a-z 0-9 - _`
Config is saved to `%APPDATA%/helios-remote/config.toml`.
## Device Labels
The device label is the sole identifier for this machine. It must follow these rules:
- Lowercase only
- No whitespace
- Only characters: `a-z`, `0-9`, `-`, `_`
Examples: `moritz_pc`, `work-desktop`, `gaming-rig`
If an existing config has an invalid label, it will be automatically migrated on next startup.
## Build
```bash
cargo build -p helios-client --release
```
