fix(chat): register --cwd as Click option for shell completion

Replace manual ctx.args parsing with a proper @click.option using
is_flag=False and flag_value='.'. This enables tab completion for
the --cwd / -C option and directory-only path completion after it.
Also bump click dependency to >=8.3.2 to avoid the optional-value
regression in 8.3.0/8.3.1.
