Tools
Tools is the cox CLI itself: the command that installs Coxswain, dispatches
work to the crew, and drives the loop from intake to landing on a branch.
What it owns
The src/tools folder holds the agent_tools package: the cox command,
its subcommands (cox install, cox setup, cox route, cox runs and the
rest), and the dispatcher that enforces the in-flight bound.
Installing it
Tools is the coxswain package's command, so installing coxswain installs
it. See Install.
Its own docs
The folder's README and docs live at src/tools.
