v0.7.0

Added

• easw hook turns on the shell hook with one command. It detects your shell and adds a marked line to its config file; easw unhook removes it. easw shell-init still prints the script for manual setup.
• The shell hook supports Command Prompt (cmd) through a doskey macro loaded by cmd's AutoRun setting. On Windows, easw hook sets up both PowerShell and Command Prompt.
• easw --help includes quick start examples.

Changed

• The README has a quick start, a full command reference with every option, and sections on the shell hook, environment variables and exit codes.
