feat: 32-bit process support, scanner rescan filtering, suppress flash on navigate

- Add pointerSize() to Provider base; WoW64/ELF detection in ProcessMemory,
  WinDbg, and RemoteProcessMemory plugins
- Wire pointer size through NodeTree, source/XML imports, C++ generator,
  controller, compose, address parser, and RPC protocol header
- Add is32Bit to PluginProcessInfo and ProcessInfo; show (32-bit) in picker
- Scanner rescan now filters results against the current input value
- Go-to-address from scanner resets change tracking to prevent false flashing
