feat(pathf): add foreign item support with is_foreign flag

Add `AnalyzeItem::foreign()` and `AnalyzeItem::local()` constructors to
distinguish items resolved via `use` imports from local definitions.
Update `GroupPattern` to collect use imports at file and module levels,
resolving `group!(TypeName)` against them.  Migrate all pattern
implementations to use the new constructors, and adjust
`type_mapping_builder` to skip the file's own module prefix for foreign
items.
