Closes #29032

This PR fixes an issue where reconnecting to SSH Remote would result in
a broken language server.

This was caused by SSH clients not registering because the `ssh_clients`
map would still contain an entry from a previously killed SSH server.
For fix, now we also check if its value has been dropped.

Release Notes:

- Fixed issue where reconnecting to SSH Remote would result in broken
code completions and diagnostics.

This PR fixes two issues:

1. On macOS, using Alt to copy the selection instead of cutting it.
2. Dropping the drag selection outside the editor dismisses it.

These models require cross-region inference, and it currently fails if
you try to use them:
```

```

I got a panic during undo but haven't been able to repro it. Potentially
a consequence of my changes in #31731

> Thread "main" panicked with "There must be at least one selection" at
crates/editor/src/selections_collection.rs

Leaving release notes blank as I'm not sure this actually fixes the
panic

Also improves some minor corner cases in `undo_selection` and
`redo_selection` related to the use of `end_selection`. If the pending
selection was ended, this would separately get pushed to the redo or
undo stack and redundantly run all the other effects of selection
change.

The use of `NamedTempFile` in #31799 was not secure and could
potentially cause write permission issues (see [this
comment](https://github.com/zed-industries/zed/issues/29528#issuecomment-2939672433)).
Therefore, it has been replaced with a Unix pipe.

We believe that collab deploys currently cause outages because:

* All clients try to reconnect simultaneously
* This causes very high CPU usage on collab (and to some extent, the
database)
* This means that collab is slow to respond to clients
* So clients timeout and retry, over and over again.

We hope by letting clients in in buckets of 512, we can accept some
minor slowness to avoid
complete downtime, while we rewrite the system.

After integrating pinned tabs into my workflow, I've come to the
conclusion that it is painfully slow to unpin all tabs by hand.


https://github.com/user-attachments/assets/ad087b8e-4595-4c4d-827f-188e36170c25

Release Notes:

- Added a `pane: unpin all tabs` action

While creating a new MCP extension this weekend, I visited these pages
and it felt like they could be improved a little bit. I'm renaming the
MCP-related page under the /extension directory to use the "MCP"
acronym, instead of "context servers".

Previously, upon hitting the "Continue" button to restart an interrupted
thread due to consecutive tool calls reaching its limit, you wouldn't
see the loading dots and the UI would be a weird state. This PR improves
when these loading dots actually show up, including in their conditional
a check for `message.is_hidden`.

Also took advantage of the opportunity to quickly organize some of these
variables. The `render_message` function could potentially be chopped up
in more smaller pieces. Lots of things going on here.

#31922 made embedded terminals automatically grow to fit the content. We
since found some issues with large output which this PR addresses by:

- Only shaping / laying out lines that are visible in the viewport
(based on `window.content_mask`)
- Falling back to embedded scrolling after 1K lines. The perf fix above
actually makes it possible to handle a lot of lines, but:
- Alacrity uses a `u16` for rows internally, so we needed a limit to
prevent overflow.
- Scrolling through thousands of lines to get to the other side of a
terminal tool call isn't great UX, so we might as well set the limit
low.
- We can consider raising the limit when we make card headers sticky.

Release Notes:

- Agent: Improve handling of large terminal output

Mostly a small tweak making sure that the indicator tooltip hit area is
bigger and the loading state is clearer (not using an indicator
anymore). Way more little improvement opportunities in this component to
do, though.

Release Notes:

Closes #5237

- Adds "trailing" option for "show_whitespaces" in settings.json
- Supports importing this setting from vscode

The option in question will render only whitespace characters that
appear after every non-whitespace character in a given line.

Release Notes:

- Added trailing whitespace rendering

Partially reverts #30682

A uniform list is desirable for the scrolling behavior, but this breaks
badly when there are collapsed entries or entries without paths, both of
which seem common with the JS adapter.

It would be nice to go back to a uniform list if we can come up with a
set of design tweaks that allow all entries to be the same height.

Release Notes:

- Debugger Beta: fixed an issue that caused entries in the stack frame
list to overlap in some situations.

Closes #32210

This notify was added in #13433. Solution is to only notify when the
breakpoint indicator state has changed.

Also improves the logic for enqueuing a task to delay showing - now only
does this if it isn't already visible, and that delay task now only
notifies if still hovering.

Release Notes:

- Fixed a bug where buffers render on every mouse move.

The dock size for the git panel wasn't being persisted across Zed

When using Deno with the example configuration as described here,
duplicate lsp information is displayed in Javascript files.

This pull request solves that issue by adding Javascript to the
configuration.

Release Notes:

- Improve LSP support when using Deno with Javascript using the default
configuration.

First of all thank you for such a fast editor!

I realized that the existing support for detecting runnable test cases
for typescript/javascript is not full. Meanwhile I can run most of test
by pressing "run button":

I was curious whether I can improve it on my own and created this pr. I
edited schemas and added minor changes in `TaskTemplate` to allow to
replace '%s' with regexp pattern, so it can match test cases:

Update the `vim::normal::search::Vim.search` method in order to
correctly set the search bar's case sensitive search option if the
`search.case_sensitive` setting is enabled.

Closes #32172 

Release Notes:

- vim: Fixed a bug where the `search.case_sensitive` setting was not respected when activating search with <kbd>/</kbd> (`vim::Search`)

Tested with following models. Hallucinates with whites outline images
like white lined zed logo but works fine with zed black outlined logo:

Pixtral 12B (pixtral-12b-latest)
Pixtral Large (pixtral-large-latest)
Mistral Medium (mistral-medium-latest)
Mistral Small (mistral-small-latest)

After this PR, almost all of the zed's llm provider who support images
are now supported. Only remaining one is LMStudio. Hopefully we will get
that one as well soon.

Release Notes:

- Add support for images to mistral models

It works similar to how deepseek works where the thinking is returned as
reasoning_content and we don't have to send the reasoning_content back
in the request.

This is a experiment feature which can be enabled from settings like
this:
