feat(pathf): add dispatch tree config and pass feature to analyzer

Add `PathfinderConfig` struct to control dispatch tree extraction,
and wire `use_dispatch_tree` through `DispatcherPattern`,
`init_with_config`,
and `analyze_and_build_type_mapping_for`. Expose config and wrapper
from `mingling_core` under the `pathf` feature.
