fix(test): prevent config file from leaking kagi token into search test

The search token validation test only cleared KAGI_TOKEN from the
environment but still loaded the user config file, which could supply
the token and cause the test to pass incorrectly. Pass
--config=/nonexistent/path so loadConfig returns an empty object.

Also includes search command improvements: markdown/json format output
and --format flag.
