fix(cli)!: remove -p short option for path argument

The -p short option is no longer needed since the path can now be
configured
via the CLAUDE_CONFIG_DIR environment variable. Users can still use
--path
for the full option name when needed.

This simplifies the CLI interface by reducing the number of short
options
and encouraging use of the environment variable for persistent
configuration.
