first round of actions

Right now, we do not use a sufficiently unique name to disambiguate
Terminal instances running on the same desktop.

Mutexes (mutants) are named objects that live in the user's session,
under `Sessions\1\BaseNamedObjects` (for the local desktop session).
When multiple users are logged into the same session--such as with "Run
as different user"--they share a local BaseNamedObjects namespace. Ugh.

We cannot use [`CreatePrivateNamespace`] as it requires a boundary
descriptor, and the only boundary descriptors supported by the current
API are based on package identity. I also fear that
`CreatePrivateNamespace` is subject to a race condition with
`OpenPrivateNamespace`; Create will not Open an existing one, so we
would need to back off and retry either opening or creating. Yuck.

After this commit, we will hash the user's SID into the name of both the
window class and the mutant, right after the path hash (if running
unpackaged).

Closes #18704

[`CreatePrivateNamespace`]:

 `setlocal` doesn't behave the same way as an environment variable. It's a thing that would have to be put in at the top of the batch script that is `somefile.cmd` as one of its first commands to adjust the way that one specific batch file is processed by the `cmd.exe` engine. That's probably not suitable for your needs, but that's the way we have to go.

 It's just that from our experience, we know there's going to be a 3-24 month bug tail here where we get massive investigation callbacks by some billion dollar enterprise customer who for whatever reason was already using the environment variable we pick for another purpose. Their script that they give their rank-and-file folks will tell them to press Ctrl+C at some point in the batch script to do whatever happens, it will do something different, those people will notice the script doesn't match the computer anymore. They will then halt the production line and tell their supervisor. The supervisor tells some director. Their director comes screaming at their Microsoft enterprise support contract person that we've introduced a change to the OS that is costing them millions if not billions of dollars in shipments per month. Our directors at Microsoft then come bashing down our doors angry with us and make us fix it ASAP or revert it, we don't get to go home at 5pm to our families or friends because we're fixing it, we get stressed the heck out, we have to spin up servicing potentially for already shipped operating systems which is expensive and headache-causing...etc.

 If I had to take an educated guess as to what is making us faster than pretty much any other application on Windows at putting your text on the screen... I would say it is because that is literally our only job! Also probably because we are using darn near the oldest and lowest level APIs that Windows has to accomplish this work.

 Why are we like this? For one, `conhost.exe` is old as dirt. It has to use the bare metal bottom layer of everything because it was created before most of those other frameworks were created. And also it maintains as low/bottom level as possible because it is pretty much the first thing that one needs to bring up when bringing up a new operating system edition or device before you have all the nice things like frameworks or what those frameworks require to operate. Also it's written in C/C++ which is about as low and bare metal as we can get.

But my manual pixel calculations, dirty region math, scroll region madness, and more makes it so we go faster than them. I'm also jealous that when someone says "hey can you add a status bar to the bottom of your window" that they can pretty much click and drag that into place with their UI Framework and it will just work where as for us, it's been a backlog item forever and gives me heartburn to think about implementing.

 As an aside, @bitcrazed wants us to automate performance tests in some conhost specific way, but I haven't quite figured out a controlled environment to do this in yet. The Windows Engineering System runs performance tests each night that give us a coarse-grained way of knowing if we messed something up for the whole operating system, and they technically offer a fine-grained way for us to insert our own performance tests... but I just haven't got around to that yet. If you have an idea for a way for us to do this in an automated fashion, I'm all ears.

 I'll give you a cursory overview of what I know off the top of my head without spending hours confirming the details. As such, some of this is subject to handwaving and could be mildly incorrect but is probably in the right direction. Consider every statement to be my personal knowledge on how the world works and subject to opinion or error.

 The portion that you're thinking of regarding "silently converted to sit on top of other stuff" is probably that once we hit the kernel calls, a bunch of the kernel GDI stuff tends to be re-platformed on top of the same stuff as DirectX when it is actually handled by the NVIDIA/AMD/Intel/etc. graphics driver and the GPU at the bottom of the stack. I think this happened with the graphics driver re-architecture that came as a part of WDDM for Windows Vista. There's a document out there somewhere about what calls are still really fast in GDI and which are slower as a result of the re-platforming. Last time I found that document and checked, we were using the fast ones.

 The trick is that GDI32 and USER32 were designed for a limited world with a limited set of commands. Desktop PCs were the only thing that existed, single user at the keyboard and mouse, simple graphics output to a VGA monitor. So using them directly at the "low level" like conhost does is pretty easy. The new platforms could be used at the "low level" but they're orders of magnitude more complicated because they now account for everything that has happened with personal computing in 20+ years like different form factors, multiple active users, multiple graphics adapters, and on and on and on and on. So you tend to use a framework when using the new stuff so your head doesn't explode. They handle it for you, but they handle more than they ever did before so they're slower to some degree.

 When we took over the console codebase, this variation between "Western" and "Eastern" countries was especially painful because `conhost.exe` would choose which one it was in based on the `Codepage for Non-Unicode Applications` set in the Control Panel's Regional > Administrative panel and it could only be changed with a reboot. It wouldn't even change properly when you `chcp` to a different codepage. Heck, `chcp` would deny you from switching into many codepages. There was a block in place to prevent going to an "Eastern" codepage if you booted up in a "Western" codepage. There was also a block preventing you from going between "Eastern" codepages, if I recall correctly.

 2. We need to scrub all usages of "Far East" from the code. Someone already started that and replaced them with "East Asia" except then they left behind the shorthand of "FE" prefixing dozens of functions which made it hard to follow the code. It took us months to realize "FE" and "East Asia" were the same thing.
 3. It's obnoxious that the way this was handled was to literally double-define every output function in the code base to have two definitions, compile them both into the conhost, then choose to run down the SB_ versions or the FE_ versions depending on the startup Non-Unicode codepage. It was a massive pile of complex pre-compilation `#ifdef` and `#else`s that would sometimes surround individual lines in the function bodies. Gross.

 On Windows, if you just run `cmd.exe` directly, the OS will create an instance of `conhost.exe` as the _terminal_ for `cmd.exe`. The same thing happens for `powershell.exe`, the system will create a new conhost window for any client that's not already connected to a terminal of some sort. This has lead to an enormous amount of confusion for people thinking that a conhost window is actually a "`cmd` window". `cmd` can't have a window, it's just a commandline application. Its window is always some other terminal.

 ## Abstract
 
-Windows Terminal's settings model adheres to a cascading settings architecture. This allows a settings object to be defined incrementally across multiple layers of declarations. The value for any global setting like `copyOnSelect`, for example, is set to your settings.json value if one is defined, otherwise defaults.json, and otherwise a system set value. Profiles in particular are more complicated in that they must also take into account the values in `profiles.defaults` and dynamic profile generators.

 The theme changes just as expected, but in an app like this, this change only affects the top of the window, leaving almost all of the screen at the mercy of what the color scheme is, and it doesn't depend on the theme, which defeats any attempt to make a good use of the `system` theme feature.

 ### Mark Mode support for degenerate range
 [PR #13053](https://github.com/microsoft/terminal/pull/13053) added support for mark mode in Windows Terminal. Mark mode allows users to create and modify selections by exclusively using the keyboard. However, screen reader users have reported it as a strange experience because it always has a cell of text selected; this results in the screen reader reading "x selected, y unselected" as opposed to the expected "x" when moving the cursor around.
