aliases: Add -local variants to run tools on the host

The opencode, claude, and pi functions wrap the tools in the Docker
container. Add opencode-local, claude-local, and pi-local so the real
host binaries can be invoked directly when container isolation is not
needed. They use `command` to bypass the wrapping functions.
