Replace DIA SDK COM-based PDB importer with RawPDB (MolecularMatters) which reads PDB files directly via memory-mapped I/O. Adds File menu "Import PDB..." dialog with type filtering, selection, and progress. - Vendor raw_pdb into third_party/ - Two-phase API: enumeratePdbTypes() + importPdbSelected() - Full recursive import of structs/unions/arrays/pointers/bitfields - PDB import dialog with name filter, select-all, type count - Benchmark: 1654 types from ntkrnlmp.pdb in 16ms - Reorganize import/export files into src/imports/
