Remote: Show GUI runs on the Windows device's interactive desktop

An application launched over SSH runs in the non-interactive session 0,
so its window lands on a desktop nobody sees. Launch runs on the
logged-on user's interactive desktop instead, via an interactive
scheduled task (schtasks /it): WindowsRunWorkerFactory flags run-mode
processes, and WindowsProcessInterface stages a PowerShell orchestrator
that creates the task, waits for it, and relays the exit code and output.

Verified on a real Windows machine over RDP. Live output streaming and
killing the remote process on Stop are follow-ups.

libptyqt: Do not write utmp records on HarmonyOS

The utmpx.h of the musl in the OHOS sysroot declares struct utmpx but none
of the functions operating on it, and no _PATH_UTMPX, so the whole block

Remote: Report failed Windows GUI runs faithfully

The interactive launcher passed the application's Windows exit status
straight out of the script, but that status reaches Creator as the exit
code of the SSH connection, which carries only its low 8 bits. A status
that is a multiple of 256 - as many crash and loader failures are, for
example 0xC0000100 - arrived as 0, so a run that died before main() was
reported as "finished successfully". Other statuses arrived as
meaningless small numbers, 0xC000012F as 47.

Pass exit codes that fit through unchanged, and turn anything else into
a failure that names the real status. A missing or unparseable exit
value now fails too instead of silently becoming 0.

Remote: Provide a real run environment for remote Windows runs

Launching an application on a native Windows device gave it an almost
empty environment, so a Qt application could not find its Qt DLLs on
PATH and exited before main().

RemoteLinuxEnvironmentAspect left the "System Environment" base empty
until the user pressed "Fetch Device Environment"; fetch it from the
device on first use instead, so a remote run starts with the device's
actual environment.

The CMake run-environment modifier only adds the target's library
directories, which on Windows are the import-lib (lib) directories,
not the DLL (bin) directory. Add the kit's Qt bin to PATH for a Windows
run device so the application finds Qt6*.dll at runtime.

Remote: Describe the interactive run launcher as it works

The comment still described the first implementation, an interactive
scheduled task (schtasks /it). What the script does is elevate to SYSTEM
through a scheduled task, because only SYSTEM may call
WTSQueryUserToken, and start the application in the active session from
there.

libarchive: Do not claim glibc-only functions on HarmonyOS

config_unix.h is generated on a glibc Linux, so it claims closefrom(),
close_range() and lchmod(). The musl of the OHOS sysroot has none of the
three, and linking libUtils failed on the first and the last. Dropping
closefrom() alone would not do, as close_range() is what libarchive falls
back to; without either it uses _SC_OPEN_MAX.

Debugger: Show CDB inferior output in the Application Output pane

When debugging with CDB without a terminal, the debuggee's stdout and
stderr (for example std::cout) did not appear in the Application Output
pane, unlike in a plain run. CDB relays the inferior's output
interleaved with its own stream; parseOutputLine() routed every
unrecognized line to the Debugger Log, so the program output was hidden
there instead of shown as application output.

While the inferior is running, such lines are the debuggee's own output,
so route them to the Application Output pane like the other engines do.
Verified on Windows/MSVC with CDB: std::cout/std::cerr now appear in
Application Output.

Profiler: Show and control debuginfod downloads

Post-processing a perf recording resolves symbols through perfparser,
which fetches debug information it does not find locally from the
debuginfod servers in DEBUGINFOD_URLS. That fetch blocks, once per build
id, so a slow or unreachable server left the Qt Profiler sitting in
"Processing captured samples" with no progress and nothing to cancel.

Make the downloads a setting, off by default, enforced by handing
perfparser an empty DEBUGINFOD_URLS, which is how elfutils is told not
to ask anyone. Cap what an unresponsive server may cost through
DEBUGINFOD_TIMEOUT and DEBUGINFOD_RETRY_LIMIT, whose defaults come to
4.5 minutes per build id. And while a download is in flight, name the
server on the recording page, with the request URL in the tool tip.

DebugInfoDownloadProgress was missing from PerfEventType::Feature, which
mirrors perfparser's wire tags, so the message never decoded.

Utils: Fix crash when a file watcher outlives the shutdown guard

The GlobalWatcher is owned by the shutdown guard, which is destroyed
at the start of PluginManagerPrivate::deleteAll(), that is, before the
plugins are deleted. A plugin holding a FilePathWatcher member thus
called removeWatch() on a null GlobalWatcher while being deleted, as
happened with the Lua plugin's user scripts watcher.

There is nothing left to unregister once the global watcher is gone,
so skip it.

Profiler: Let the perf MCP tool start the way its action does

start_perf_profiler called runStartupProject() directly, so unlike the
Performance Analyzer menu entry and unlike start_profiler it left the
Profile mode unselected. Give the tool a profileStartupProject() used by
both. The QML side keeps its extra step, discarding a previous trace
after asking about unsaved notes, which perf does not need: it clears
its trace when the next one starts.

Both tools' instance() is reachable from MCP requests while the perf
tool is already deleted by aboutToShutdown(), so clear the instance
pointer in the destructor, as the QML tool does, and report the missing
tool instead of dereferencing it.

Also state why start_profiler and start_perf_profiler exist next to
run_project, which reaches the same run modes by id: they return
immediately, so status and stop tools can drive the session.

DiffEditor: Collapse unchanged lines in the inline diff

Add a toolbar toggle to the inline diff editor that hides runs of
unchanged lines, keeping a few context lines around each change and
replacing each hidden run with a clickable "Show N hidden lines"
placeholder that reveals it again. The toggle is on by default and
its state is persisted. It works in both the inline and the side by
side view, where both sides are collapsed at their corresponding
lines so the aligner keeps the two views lined up row by row.

The inline diff editor shares its document with the regular editors,
so real folding via QTextBlock::setVisible() cannot be used: it would
collapse the same lines everywhere. Instead TextEditorLayout gains a
per-widget "editor-hidden block" concept - hidden blocks report zero
height and line count and are skipped in this widget's paint, scroll,
gutter and navigation only. It stays inert for every editor that does
not opt in, behind a hasEditorHiddenBlocks() guard.

The CollapseController computes the collapsible runs on the editor
side and maps each to the matching baseline lines through the diff
offset, so a pure insertion or deletion collapses consistently on
both sides. It hides the runs in each view's own layout and floats
the placeholder rows; naturalBlockHeight() treats hidden blocks as
zero so the side by side aligner stays consistent.

Add testInlineDiffCollapse and testInlineDiffCollapseAddedLines,
covering both views, the toggle, the gutter line numbers, the row
alignment and the pure-insertion case.

Debugger: Use native incremental breakpoints in BridgeEngine

Replace the copied DAP declarative setBreakpoints model (whole-source
replace with fragile file:line correlation) with incremental
qtc/insertBreakpoint / updateBreakpoint / removeBreakpoint requests.

Parameters are serialized with the shared addToCommand(); responses are
correlated by the stable modelid, never by file:line. The bridge returns
the breakpoint in the MI 'bkpt' shape (with a sub-location list), which
the C++ side feeds to the shared updateFromGdbOutput()/handleBkpt() - the
same path GdbEngine uses - so sub-breakpoints are populated as first-class
children.

Verified end-to-end against real gdb: insert returns a resolved bkpt and
the inferior stops at the breakpoint.

Still to do: qtc/enableSubBreakpoint, the async qtc/breakpointChanged
event, and demangling the location function name.

Docker: Do not hardcode the X11 display

X11 forwarding always passed DISPLAY=:0 into the container on Linux
hosts. That fails on any session that is not :0, which is common on
Wayland setups where XWayland runs as :1.

Derive the display from the host's DISPLAY instead. A local display
name applies verbatim, since the host's X11 socket is mounted into the
container. Anything else has to reach the X server over TCP, so only
the display number is taken over from the host.

Add an "X11 display" device setting to override the derived value.
Leaving it empty keeps the derived value, so it follows the current
session instead of freezing a stale display into the device
configuration.

Profiler: Say why a perf recording captured no samples

"No samples were captured" named two possible causes and left the user
to guess between them, while the processes that knew the answer had
already given it and been ignored: "perf record" writes the reason it
could not open events to stderr, and perfparser rejecting an argument
or giving up mid-stream was reported as an empty recording rather than
as its own failure.

Keep both streams and report what they say. Read perf_event_paranoid
when it is the restriction in force, so the message can name the level
and what it has to be. Count the samples perfparser delivered, which
separates "nothing was sampled" from "nothing resolved to a call
stack" -- two problems with nothing in common but an empty trace.

offers one by re-reading perf_event_paranoid after a failed recording,
so the button appears only while the change is still needed, and the
Qt Profiler runs it through pkexec, which asks for the password in its
own dialog -- sudo would read from a tty a GUI does not have.

Applying it starts the recording again; that is the whole
confirmation, so there is no second dialog to dismiss. Dismissing the
password prompt is a deliberate no and passes silently.
