test: cover claude code skip permissions args

[TechWizard9999]

Summary

• extract Claude Code CLI argument construction into a small helper
• add regression tests for --dangerously-skip-permissions in complete mode
• add regression tests for --dangerously-skip-permissions in streaming mode

Testing

• CARGO_TARGET_DIR=/tmp/librefang-target cargo test -p librefang-runtime claude_code

Nice refactor — extracting build_command_args eliminates the duplicated arg construction between complete and complete_stream. The three test cases cover the key combinations (skip_permissions on/off, verbose on/off). LGTM.

Code review: LGTM

• Refactoring is logic-equivalent — build_command_args() correctly extracts all CLI arg construction from both complete() and stream()
• Argument order change (--model before --add-dir) is irrelevant for CLI flag parsing
• Test coverage for --dangerously-skip-permissions on/off is solid
• Minor nit: .to_string() on &str args is redundant but harmless

Clean PR, no issues found.
