- Add Fadec x86 disassembler with hover popup for FuncPtr/void Pointer nodes - Separate pointer symbol from address: // prefix, green comment coloring, independent hover/click zones (address triggers popup, symbol is passive) - Fix RVA margin and inline local offset for pointer-expanded vtable children using ptrBase field threaded through composition - Expand multi-select context menu with quick-convert, duplicate, copy address - Remove Edit Value from hex node context menu - Fix heatmap flickering on hex nodes (remove per-byte alternation) - Fix popup repositioning when moving mouse between lines - Truncate disasm popup to 6 lines with ... indicator - Add BUILD_UI_TESTS option to skip widget tests on headless CI - Add test_disasm with 35 test cases for disassembly and hex dump - Add KUSER_SHARED_DATA example .rcx file
