refactor(manifest): replace get_suggested_resource_type with local functions

Remove dependency on Paths.get_suggested_resource_type() and replace with
two new local functions:
- get_local_resource_type(): determines resource type based on path patterns
- get_relative_path_for_type(): extracts relative path for specific types

This change simplifies the autoprovides_scan_tree logic and eliminates the
ROOT_PATH resource type, defaulting to "res" for unrecognized paths.
