fix: move extractScopeAndTags to base Input — runtime cast was invalid

The (input as NoteInput) cast is TypeScript-only; at runtime Parser
receives plain Input objects from parseInput(), causing
"extractScopeAndTags is not a function". The service contract
resolveNotePathForInput(input: Input) requires the method on Input.
