Debugger: Add a start_debug MCP tool

Pair a start_debug tool with the existing stop_debug tool in the
debugger plugin, so an MCP client can start a debug session for the
startup project (DEBUG_RUN_MODE) and drive debugging end to end.

Drop the overlapping debug_project tool from the ProjectExplorer MCP
support; debug-session control now lives solely in the debugger
plugin. Building is left to the separate build tool.

Lua: Add a Mode module

Let Lua plugins contribute a mode (a left-side tab with its own
full-window widget): Mode.create{ id, displayName, widget, priority?,
icon? } creates and shows it, and removes it again when the plugin is
unloaded.

For this ModeManager::addMode() has to work after startup too. It was
startup-only (the initial batch is laid out at extensionsInitialized);
now a mode added later builds its tab as well. IMode's constructor
calls addMode() before the caller sets id/widget/..., so the tab
creation is deferred to the next event-loop turn, when the mode is
fully configured.

ProjectExplorer: Report run configuration details in the MCP tool

get_run_configurations returned only the display name and the active
flag. Also report the run configuration's type id and its resolved
runnable: executable, arguments, working directory, and the full run
environment. A client can then see what a run will actually execute
and in which environment (for example whether Qt's bin is on PATH)
without extra round-trips.

ProjectExplorer: Add an MCP tool to create a build configuration

The MCP server could list, switch and query build configurations, but
not create one. A CMake project on a freshly set up kit typically has
only a Debug configuration, so there was no way to build or run in
Release over MCP.

Add add_build_config: it creates a build configuration for the active
project's kit from the requested build type (matched against the kit's
available build types), names it, and makes it active unless set_active
is false. On a type mismatch the error lists the available types.

ProjectExplorer: Add an MCP tool to remove kits

detect_device_tools creates a kit per toolchain it finds on a device,
and nothing could remove one again, so kits accumulated with no way to
clean up after a device.

remove_kits takes kit ids or display names. It refuses SDK-provided
kits, as the Kits preferences page does, and refuses a display name
that several kits share, since the removal cannot be undone.

CMakeProjectManager: Add an MCP tool to reset the configuration

A build directory whose first configure failed keeps a CMakeCache
without the initial arguments, and re-running CMake reuses that cache,
so the project cannot be brought back over MCP - the recovery, Build >
Clear CMake Configuration, had no tool.

reset_cmake_configuration clears the active build configuration and,
unless reconfigure is false, configures it again from scratch. Like the
action, it refuses to run while the project is building.

CMakeProjectManager: Don't report a failed CMake run as succeeded

When CMake fails while the build directory still holds the file-api
reply of an earlier successful run, Creator parses that stale data and
reports a successful parse, so the MCP reconfigure tool answered
succeeded: true next to the errors it had just produced - and its output
schema tells callers to trust that field over the issues array.

Take the build system's error into account, which is set just before the
parse finishes, and name it in the summary.

Process stub: Suspend the inferior on FreeBSD for debugging

In "Run in Terminal" debug mode the stub must suspend the inferior so
the debugger can attach to it. That was implemented for Windows
(CREATE_SUSPENDED), macOS (raise(SIGSTOP)) and Linux (PTRACE_TRACEME),
but there was no path for FreeBSD, so the inferior ran unsuspended and
gdb's attach raced it: the launch hung in "Launching Debugger" and
timed out (non-terminal debugging was unaffected).

FreeBSD can use the same approach as macOS: the child raises SIGSTOP,
and since QProcess does not report the pid when the child stops before
execve, the pid is passed via shared memory and a poll timer. Route
FreeBSD through that code with a shared STUB_SIGSTOP_SUSPEND guard.

Debugger: Do not steal terminal focus on transient startup stop

When debugging a console application "in terminal", the inferior is
launched suspended by the process stub, so the debugger sees an initial
spontaneous stop right after start-up. notifyInferiorSpontaneousStop()
then raised Qt Creator to the foreground (RaiseOnInterrupt), stealing
focus from the just-opened terminal before immediately continuing the
inferior.

Defer the raise by one event loop cycle and skip it if the engine has
meanwhile left InferiorStopOk. A genuine stop (breakpoint, signal, user
interrupt) stays stopped and still raises; a transient start-up stop
that is immediately continued no longer does.

Valgrind: Note filtered issues in the Memcheck status message

The "N issues were found" message counted all issues from the source
model, while the result view shows only the ones passing the current

stayed empty, with no hint why.

Append the number of issues hidden by the filter, mirroring the Clang

matches it literally, while the bare bracket made the translated pattern
invalid and it then matched nothing.

FakeVim: Grow the runtime surface Vim9 plugins expect

Enough for Vim 9.1's bundled comment.vim to load and run unchanged:
"gc{motion}", "gcc", "gC" and the visual-mode "gc" toggle comments, and
toggling twice restores the text.

Vim9 parsing: ":def" nests, since a nested one is defined when the outer
function runs and the body has to be collected up to the matching end.
"...name: type" binds the extra arguments under that name. A statement
may be a bare call to a lowercase function such as add(), so only the
statement keywords are excluded now. What follows a command modifier is
a statement too and is rewritten the same way.

New commands and builtins: the mark- and jump-preserving modifiers
(":noautocmd", ":keepjumps" and friends), "import autoload" resolved
against the autoload directory next to the importing script, a guard
against a script sourcing itself (which recursed until the stack was
gone), expand() with <stack>/<sfile>/<cword>, escape(), indent(),
setline() taking a list, a bare scope name as a dictionary so
get(g:, ...) works, and the 'commentstring' and 'modifiable' options.

expand('<stack>') has to report a name that can be called again: plugins
pull one out of it to install their own 'operatorfunc'.

FakeVim: Derive 'commentstring' from the file type

The option held one global value, so a script commenting a .pro or .py
file inserted "//". It is now buffer-local as in Vim and resolved from
the file type set with ":setf", falling back to the file name extension
and then to the configured default. An explicit ":set commentstring="
still wins and stays with its buffer.

"gc" reads the same value instead of keeping a second table of comment
leaders, and honors a trailing part, so it comments an HTML file with
"<!-- ... -->" rather than "//".

FakeVim: Detect the file type of an opened buffer

The buffer read autocommands were accepted by ":autocmd" but never
fired, so the usual "autocmd BufRead,BufNewFile *.py setf python" never
ran and 'filetype' stayed empty unless someone typed ":setf". Fire
BufReadPost or BufNewFile when an editor opens, and BufEnter/BufLeave
when one becomes or stops being current. "BufRead" and "BufReadPost"
name the same event and now match each other.

The type itself comes from Qt Creator's MIME database rather than from a
copy of Vim's filetype.vim: it already matches file names and file
contents to pick an editor and a highlighter, which also settles cases
an extension cannot, such as CMakeLists.txt. Only a rule that no read
autocommand claimed is filled in, so a vimrc keeps the last word.

'filetype' is readable as &ft now, which scripts test to decide what a
buffer holds, and 'commentstring' follows the detected type.

FakeVim: Follow Vim's did_filetype() rule in :setf

":setf" claimed a buffer unconditionally, so with two detection rules
matching it the last one won instead of the first. It now sets the type
only when did_filetype() is false, which Vim defines as "the FileType
event has fired for this buffer while autocommands are running": the
first rule to recognize a buffer wins, reading it again starts over, and
an interactive ":setf" still applies because no autocommand is running.
"setf FALLBACK {name}" marks a guess that a later ":setf" may replace,
which is how the type derived from the MIME database is installed.

did_filetype() is available to scripts, since detection scripts test it
before doing work.

The FileType event may now fire from within another autocommand, so a
":setf" in a buffer read rule reaches the FileType rules as it does in
Vim. Deeper chains are still cut off. ":noautocmd" no longer shares its
flag with the nesting guard, which had made it mean two things at once.

FakeVim: Obey modelines

A "vim:" line in the first or last lines of a file was ignored, so a
file could not state how it wants to be edited. Both documented forms
are read, the one whose options run to the end of the line and the
"set ... :" one that fits inside a comment, along with the version
requirements ("vim>702:") and the rule that the marker has to start a
line or follow a blank so that a word ending in "vim:" is not one.

'modeline' and 'modelines' control it, as in Vim.

Modelines are applied after the file type has been established, so a
file saying "ft=python" wins over what was detected for it.
