Adds the source location column to the breakpoint list, the last of the places
worth surfacing line info. Exec breakpoints get a real location; memchecks and
register breakpoints get "-", since a watched data range and a register aren't
tied to a code address.
Fixed a pre-existing misalignment found while adding the column: the register
breakpoint row never emitted a cell for the Log column, so every following cell
sat one to the left - the register name appeared under "Type", the condition
under "OpCode" and the hit count under "Cond", with the last column left blank.
It has a Log checkbox now like the other two rows (register breakpoints do
support the log action), and the register name moved to Size/Label where the
memcheck row puts its size.
AGENTS.md gets what this stretch of work turned up:
- Most files here are CRLF, including every .vcxproj, Android.mk,
Makefile.common and AGENTS.md itself. Patching one with a script that reads
with universal newlines and writes with newline='' silently rewrites the whole
file - it turned a two-line addition into a 5000-line diff, which is invisible
in an editor and obvious in git diff --stat.
- Don't pipe Python containing backslashes through a bash heredoc; the quoting
mangles them and anchors just fail to match for no visible reason.
- Headless registers its own debug-output listener, so exception and crash
messages never reach the log - they go to stdout, block-buffered when
redirected, and taskkill //F discards the buffer instead of flushing. Give the
run a short --timeout and let it exit if you need to read a crash trace.
- 0xFFFFFFFF decodes to vflush, a real VFPU instruction, so it's useless as
"garbage" for testing illegal-instruction handling.
- A wsdbg script has to stay connected long enough for what it asked for; ending
with :quit straight after cpu.runUntilTime looks exactly like a broken feature.
- Where DWARF line info is and isn't available, since it's much narrower than it
sounds.
- Corrected the note claiming broadcast.config.set only accepts logger and
input; it takes all five categories now.

Following on from the DWARF line table: the lookup was only reachable from
hle.backtrace, the breakpoint hit object and the ImGui disassembly status bar.
Now also in
- the ImDebugger call stack (new Source column),
- the Win32 call stack (new Source column),
- the Win32 disassembly status bar, matching the ImGui one,
- the ImDisasmView right-click menu, which showed a bare address as its heading
and now leads with "mesh.zig:163 (08841f98)" when there's a line for it,
- breakpoint log lines - a log-only breakpoint's entire output is those lines,
and "BKP PC=08841f98 mesh.zig:163" reads a great deal better than an address
when you're scanning a few thousand of them,
- crash stack traces, via FormatStackTrace, which is what the crash screen and
crash reporting both use.
That last one is where it earns its keep, and it needed the invalid-jump path to
produce a stack trace at all - it was the one exec exception that didn't. It's
also the one that most deserves it: the address it jumped to tells you nothing,
the callers tell you everything. Execution has already moved to the bad address
by the time it's noticed, so a walk from pc finds no function to start from;
WalkCurrentStack takes an explicit starting pc now, and falling back to ra
recovers the chain. Reproducing the original CrossCraft bug:
CPU Jump: Invalid jump to ae870000 from PC ae870000(invalid) RA 08841f98
MIPS call stack:
rendering.mesh.Mesh(PspVertex).draw at mesh.zig:163 (08841c30+368, ...)
state.MenuState.draw at MenuState.zig:821 (0883ab90+414, ...)
engine.Engine.stepFrameInternal at State.zig:40 (08820f74+5164, ...)
utils.module._module_main_thread at engine.zig:468 (088272c4+2fb8, ...)
Fixed a pre-existing double-report while in there: every case in
Core_ExecException sent its message and then fell through to an unconditional
send of the same message, so each exec exception was logged twice. The message
is built in the switch and sent once at the end now.

The block list in the memory windows was navigation-only - click to jump there,
and that was it. Right-clicking a block now offers the two things you actually
want once you've found one:
- Copy info to clipboard. More than the status bar shows (range, size, the PC
that allocated it, ticks, flags, allocated state), since the reason to copy it
is to keep it - for a bug report or to compare two runs.
- Add memory breakpoint, covering the whole block rather than a single address.
That's the point of doing it from this list: you want to catch anything
touching the allocation, not one byte of it. Read and write, pause and log.
It then opens and focuses the Breakpoints window, via a new SHOW_IN_BREAKPOINTS
command so window activation stays with the other ImCmds rather than poking at
the config from here.
Only on the blocks themselves, not on the synthetic "(start)" and "(end)"
entries, which have no block info behind them to copy or watch.

step-over, step-out and run-until plant a one-shot breakpoint at the address
they want execution to return to. Keeping it in breakPoints_ alongside the
user's own meant the two kept colliding:
- Adding a log-only user breakpoint at the same address hijacked the temporary
one. AddBreakPoint() didn't match across temp-ness so both existed, and then
ChangeBreakPoint() looked up "the first enabled breakpoint at this address" -
a log-only breakpoint isn't enabled, so the temporary one won and had its
action overwritten to log-only. It lost PAUSE and the step never came back.
- RemoveBreakPoint() erased up to two entries per address to catch an
overlapping temporary one, so deleting either deleted both - including the
interpreter's cleanup path in CheckExecBreakpoints() taking the user's
breakpoint with it.
- ExecBreakPoint() handled one breakpoint per address, so with both at the same
address only one of them did anything: the step completed but the user's log
line never printed.
- Nothing dropped it when something *else* stopped us first, so an interrupted
step left a breakpoint armed at an address nobody was waiting for anymore,
which later fired as a phantom stop.
It's a single TempBreakPoint member now, invisible to the breakpoint lists and
untouched by user edits. One is enough: step over/out and cross-thread step into
all require the CPU to already be stepping and resume it immediately, so only
one can be in flight, and run-until now replaces rather than stacking (two
pending run-untils had no coherent meaning, and the loser stayed armed).
Behavior follows what other debuggers do. Both breakpoints at an address are
evaluated independently and their actions combine, so a log-only breakpoint
logs without stopping and still lets the step finish. Core_Break() drops the
temporary breakpoint on any stop, whatever the reason - the same way gdb deletes
its step-resume breakpoint and lldb discards the thread plan.
Two things to be careful of, both covered by the new TempBreakpoints test:
HasBreakPoints() has to account for it, or the interpreter's checked run loop
and the JIT skip breakpoint checking entirely and a step with no user
breakpoints set never returns; and IsAddressBreakPoint() (user-facing, for the
lists and disassembly markers) is now separate from NeedsBreakCheckAt() (what
the JIT frontends and interpreter ask), since only the latter should see it.

ChangeBreakPointAddress() moves the breakpoint keeping its action, condition and
log format, invalidates both ends, refuses to land on an existing breakpoint,
and resets the hit count since it belonged to the old address. The edit form now
works on a copy of the address and commits on deactivation rather than per
keystroke, so typing one address doesn't churn through every prefix of it.
The breakpoint edit form assigned straight to bp.addr and then invalidated the
icache at "bp.addr - 4, 8" - which by then is the *new* address - need both.
Also clear the selection after Delete in both edit forms - the reference into
the vector is dangling from that point on. Harmless today, but only because
nothing happens to touch it below.
Covered by a new Breakpoints unit test (verified to fail without the duplicate
check and the hit reset).

AddLabel() won't overwrite an existing label. That's deliberate and right for
bulk import - a real ELF symbol name shouldn't lose to the analyzer's later
z_un_* - but wrong when someone is explicitly naming an address, so a second
hle.data.add at the same address silently kept the old name. The response echoed
the requested name back either way, so there was no sign anything had been
ignored.
Force the requested name in with SetLabelName() now, except when a function
starts at that address and owns the label - renaming that function isn't what
"label this data" should mean, and it would undo the care hle.data.remove takes
not to destroy it. Either way the response now reports the name the symbol
actually ended up with rather than the one that was asked for.
Also, in the ImDebugger memcheck edit form: the Enabled checkbox didn't mark the
memcheck as changed, and the condition combo marked it changed on every frame
the popup was open rather than when a condition was actually picked (Selectable
returns true only on click, BeginCombo stays true while open).
