Bug fixes: - InputSimulator: Pass correct button state (MK_LBUTTON/MK_RBUTTON) in wParam for button-down messages instead of 0. - PeHeaderParser: ParseOptionalHeader now reads only the optional header, not section headers (fixes double-parse waste). - EntryPoint: Removed useless isPe32Plus branch (AddressOfEntryPoint is at offset 16 in both PE32 and PE32+). - RemoteWindow: Handle null foreground window case in Activate to avoid calling GetWindowThreadProcessId with HWND 0. - RemotePointer: Remove dead null-conditional operators (encoding ??) since encoding is non-nullable. Constants added: - SystemMethods: MkLButton (0x0001) and MkRButton (0x0002) for mouse button state flags. Tests: 199 passing, 4 integration/interactive skipped.
