Fixes a regression introduced in
https://github.com/zed-industries/zed/pull/34992

### Background

Paths are rendered first to an intermediate MSAA texture, and then
copied to the final drawable. Because paths can have transparency, it's
important that pixels are not copied repeatedly if paths have
overlapping bounding boxes. When N paths have the same draw order, we
infer that they must have disjoint bounding boxes, so that we can copy
them each individually (as opposed to copying a single rect that
contains them all). Previously, the bounding box that we were using to
copy paths was not accounting for the path's content mask (but it is
accounted for in the bounds tree that determines their draw order).


This cause bugs like this, where certain path pixels spuriously had
their opacity doubled:

This PR fixes that bug.

* [x] mac
* [x] linux
* [x] windows

Release Notes:

- Fixed a bug where a selection's opacity was computed incorrectly when
it overlapped with another editor's selections in a certain way.

This _should_ allow sentry to associate related panic events with the
same issue, but it doesn't change the issue title. I'm still working on
figuring out how to set those fields, but in the meantime this should at
least associate zed versions with crashes

Fixes https://github.com/zed-industries/zed/issues/33257

Previously, the scale-factor-change-handling logic relied on
`SetWindowPos` enqueuing a `WM_SIZE` window event. But that does not
happen when the window is maximized. So when the scale factor changed,
maximized windows neglected to call their `resize` callback, and would
misinterpret the positions of mouse events.

This PR adds special logic for maximized windows, to ensure that the
size is updated appropriately.

> Any user interaction that is equivalent to a click, such as pressing
the Space key or Enter key while the element is focused. Note that this
only applies to elements with a default key event handler, and
therefore, excludes other elements that have been made focusable by
setting the

attribute.

When you switched away from an ACP thread, the `AcpThreadView` entity
(and thus thread, and subprocess) was leaked. This happened because we
were using `cx.processor` for the `list` state callback, which uses a
strong reference.

This PR changes the callback so that it holds a weak reference, and adds
some tests and assertions at various levels to make sure we don't
reintroduce the leak in the future.

This PR changes the signature of `language_names` from

```rust
pub fn language_names(&self) -> Vec<String>
// Into
pub fn language_names(&self) -> Vec<LanguageName>
```

The function previously eagerly converted `LanguageName`'s to
`String`'s, which requires the reallocation of all of the elements. The
functions get called in many places in the code base, but only one of
which actually requires the conversion to a `String`. In one case it
would do a `SharedString` -> `String` -> `SharedString` conversion,
which is now totally bypassed.

This PR adds handling for the case where the user's gemini-cli binary
fails to start up because it's too old to support the
`--experimental-acp` flag. We previously had such handling, but it got
lost as part of #35578.

This doesn't yet handle the case where the server binary exits
unexpectedly after the connection is established; that'll be dealt with
in a follow-up PR since it needs different handling and isn't specific
to gemini-cli.

Allows tabbing through everything in all three pages. Until #35075 is
merged it is not possible to actually "click" tab focused buttons with
the keyboard.

Additionally adds an action `onboarding::Finish` and displays the

Building" buttons, with the keybind displayed similar to how it is for
the page nav buttons

This change adds the current tab index functionality to buttons and
implements a proof of concept for the new welcome page.

Primarily blocked on https://github.com/zed-industries/zed/pull/34804,
secondarily on https://github.com/zed-industries/zed/pull/35075 so we
can ensure navigation always works as intended.

Another thing to consider here is whether we want to assign the tab
order more implicitly / "automatically" based on the current layout
ordering. This would generally enable us to add a default order to
focusable elements if we want this. See [the
specification](https://html.spec.whatwg.org/multipage/interaction.html#flattened-tabindex-ordered-focus-navigation-scope)
on some more context on how the web usually handles this for focusable
elements.

Before, each time any LSP feature was used on client remote, it always
produced a `proto::` request that always had been sent to the host, from
where returned as an empty response.

Instead, propagate more language server-related data to the client,
`lsp::ServerCapability`, so Zed client can omit certain requests if
those are not supported.

On top of that, rework the approach Zed uses to query for the data
refreshes: before, editors tried to fetch the data when the server start
was reported (locally and remotely).
Now, a later event is selected: on each `textDocument/didOpen` for the
buffer contained in this editor, we will query for new LSP data, reusing
the cache if needed.

Before, servers could reject unregistered files' LSP queries, or process
them slowly when starting up.
Now, such refreshes are happening later and should be cached.

This requires a collab DB change, to restore server data on rejoin.

Release Notes:

- Fixed excessive LSP requests sent during remote sessions

Closes: https://github.com/zed-industries/zed/issues/23704

Existing action is `editor::ToggleEditPrediction` ("This Buffer").
This action is `workspace::ToggleEditPredction` ("All Files").

You can add a custom keybind wi shortcut with:
```json
  { "context": "Workspace", "bindings": { "ctrl-alt-cmd-e": "workspace::ToggleEditPrediction" } },
```

This is a bit of a readability improvement IMHO; I often find myself
confused when dealing when dimension pairs, as there's no easy way to
jump to the implementation of a dimension for tuples to remind myself
for the n-th time how exactly that impl works. Now it should be possible
to jump directly to that impl.

Another bonus is that Dimension supports 3-ary tuples as well - by using
a () as a default value of a 3rd dimension.

This PR fixes a bug where a file remained in a Created state after

instead of reverting back to previous state. Now it changes it to

delete the file instead of reverting to previous accepted state.
