PrintRegValue returned "N/A" for the VFPU category, and CtrlRegisterList
had its WM_VSCROLL case commented out, so only the rows that fit in the
window were reachable - about a quarter of the 128 VFPU registers. Print
the float the same way the FPU tab does, give the list a real scrollbar
with mouse wheel support, keep the keyboard selection in view, and reset
the position when switching tabs.
The category header hit test now uses the client rect so the tab
boundaries match what's drawn once the scrollbar takes its share of the
width. KernelThreadDebugInterface gets the same one-line fix for parity.
It stopped being about memory when CPU_Shutdown started holding it across the
whole teardown - it's what keeps kernel objects, the symbol map and the memory
map from being freed while another thread reads them. The old name invited the
reading that it locks memory *access*, which it has never done.
Memory::Reinit() now holds it across both halves rather than relying on
Memory::Shutdown()'s own acquire: between Shutdown() and Init() there is no
memory map at all, and a reader could slip into that gap.

Seven GUI-thread readers held only g_frameMutex, which guards against the CPU
thread mutating state but not against the core being torn down - and two of
PSP_Shutdown's paths (EmuScreen::sendMessage, ProcessScreenSwitches) run outside
that span entirely. CtrlThreadList::reloadThreads walking kernel objects that
__KernelShutdown had freed was the concrete crash; the symbol map readers
(CDisasm::Show/NotifyMapLoaded, CtrlModuleList, CtrlWatchList) had the same
shape.
Always g_frameMutex first, then Memory::Lock().

Debugger windows (register list, disassembly view, memory view, breakpoint/
thread/module/stack lists, watch list) read CPU-thread-owned state directly
from the GUI thread's WM_PAINT/list-fill handlers, racing against the CPU
thread. Routing every read through Core_RunOnCPUThread would be too slow for
something invoked continuously on paint/list-refresh.
Add g_frameMutex (Core.h/Core.cpp), held by NativeFrame() only across the
span where it actually touches that state (running the CPU, processing
breakpoints, running the ImGui debugger) - not across input handling or the
present/frame-pacing waits. Debugger windows now hold the same mutex while
reading, giving synchronized reads without the round-trip cost of queuing
to the CPU thread.
CtrlRegisterList::onPaint() goes back to always reading live values (now
safe under the lock) and grays them out by color alone while the core is
running, rather than the earlier snapshot-caching approach.

The Win32 debugger dialogs mutate CPU-thread-owned state (breakpoints,
symbol map, registers, memory, kernel threads) directly from the GUI
thread with no synchronization, same problem the WebSocket debugger had.
Route all of these through Core_RunOnCPUThread instead, following the
same pattern used there.
Also drops two forced-pause (Core_Break/Core_WaitInactive/Core_Resume)
dances in CtrlMemView::onChar and DumpMemoryWindow's dump handler, now
unnecessary since Core_RunOnCPUThread works whether the CPU is running
or already stepping.
Modal dialogs (MessageBox, InputBox_GetString, BreakpointWindow::exec,
etc.) are kept outside any queued callback so they never block the CPU
thread on user input. Pure reads/painting (disassembly formatting,
search, list reloads, onPaint) are intentionally left as-is for now.

make the rightclick work in the registerlist for all displayed registers.
The LO HI and PC registers couldn't be rightclicked previously.
Also, if you rightlick a valid row and then rightclick on the leftmost 16
pixels you'd get the popup menu for the old selection (even on invalid y
indices).
Make the "change register value"-dialog start with '0x' because otherwise
values starting with an alphabetical hexadecimal symbol will yield
be parsed as a symbol instead of a number and yield 'unknown symbol'
