KeySync CLI 0.1.70

Requirements:
- Linux x64 or arm64
- Node.js 24 or newer available on PATH

Usage:
  ./keysync login --email you@example.com --password 'your-password'

Login stores the session, prepares the current device, and starts the background daemon automatically.

Useful commands:
  ./keysync status
  ./keysync doctor
  ./keysync logout

Advanced:
  ./keysync login --no-start-daemon --email you@example.com --password 'your-password'
  ./keysync daemon --interval-seconds 30

The CLI stores local state by server host under the current user's application data directory.
Use KEYSYNC_STATE_DIR=/path/to/state to override it for testing.
