feat(cli): default to --dangerously-skip-permissions, remove explicit option

Always forward --dangerously-skip-permissions to claude binary without
requiring the user to pass the flag manually. Removes the option from
help output and CLI signature.

- Remove --dangerously-skip-permissions click option
- Always append the flag to the claude command
- Update tests to assert default behavior and help output
- Extend .gitignore with desktop build/release directories
