rajatnagda45 786e8868a0 fix(extract): drop Swift generic type parameters from references
A `struct Stack<Element>` / `func map<R>(...)` binds `Element`/`R` as local
names, not corpus symbols, but `_swift_collect_type_refs` appended the bare
identifiers used in a signature or stored-property type as type references and
ran them through the sourceless-stub path. Every generic type/function in the
corpus then collapsed its `T` onto one bare `t` node — a god node that pollutes
god-node rankings, since single-letter type parameters are not in the
analyzer's builtin-noise filter. C#, Java, TypeScript, Kotlin, Scala, C++, and
Go already exclude theirs.

Mirrors that pattern (and complements the `Self` keyword fix already in this
collector): a new `_swift_type_parameters_in_scope` helper walks up to every
enclosing declaration's `type_parameters` list and takes each `type_parameter`'s
first `type_identifier` as the bound name (a constraint like `T: Equatable` is a
separate `user_type`, left to reference), and `_swift_collect_type_refs`
auto-computes and threads that skip set. Genuine user types and the `Int`/
`String` builtin hubs are unaffected.
