fix: persist guidance filename in project config for enhance flow

The enhance command re-invokes itself via subprocess with saved config
args. Without persisting agent_guidance_filename, it always defaulted
to GEMINI.md, creating a duplicate file instead of merging into the
correct one (e.g., CLAUDE.md).

- Persist agent_guidance_filename in create_params across all templates
  (Python, Go, TypeScript, Java) when non-default
- Pass agent_guidance_filename through cli_override_args in enhance
