extractPdbSymbols() was reading S_GDATA32/S_GTHREAD32 records which
contain a typeIndex field linking the symbol to its type definition in
the TPI stream, but this field was discarded — only name + RVA were
kept. This meant loading symbols gave you address resolution but no
way to automatically import the type associated with a global variable.
Changes:
- PdbSymbol now carries typeIndex (0 = no type info / public symbol)
- extractPdbSymbols() captures typeIndex from all global data symbols
- PdbSymbolSet stores nameToTypeIndex mapping alongside nameToRva
- New importTypeForSymbol() follows LF_POINTER/LF_MODIFIER chains to
find the underlying UDT/enum and imports it with full recursive children
- New symbols.importType MCP tool: given "ntdll!g_pShimEngineModule",
resolves its typeIndex, imports the type definition from the PDB, and
merges it into the active project
- loadPdbIntoStore() helper consolidates the extract+store pattern with
type index support
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/
