Previously _route_config only forwarded --dry-run, silently dropping
all enhancement workflows, --merge-mode, and --skip-codebase-analysis.
Changes:
- arguments/create.py: add CONFIG_ARGUMENTS dict with merge_mode and
skip_codebase_analysis; wire into get_source_specific_arguments(),
get_compatible_arguments(), and add_create_arguments(mode='config')
- create_command.py: fix _route_config to forward --fresh, --merge-mode,
--skip-codebase-analysis, and all 4 workflow flags; add --help-config
handler (skill-seekers create --help-config) matching other help modes
- parsers/create_parser.py: add --help-config flag for unified CLI parity
- tests/test_create_arguments.py: import CONFIG_ARGUMENTS; update config
source tests to assert correct content instead of empty dict
