Our provider code in `language_models` filters out messages for which
`LanguageModelRequestMessage::contents_empty` returns `false`. This
doesn't seem wrong by itself, but `contents_empty` was returning `false`
for messages whose first segment didn't contain non-whitespace text even
if they contained other non-empty segments. This caused requests to fail
when a message with a tool call didn't contain any preceding text.

{up,down,left,right}` to `ctrl-alt-{up,down,left,right}`. `ctrl-k` is

Release Notes:

- vim: add cursor shape settings for each vim mode

---

Add cursor shape settings for each vim mode to enable users to specify
them.

Example of `settings.json`:

```json
{
  "vim_mode": true,
  "vim": {
    "cursor_shape": {
      "normal": "hollow",
      "insert": "bar",
      "replace": "block",
      "visual": "underline"
    }
  }
}
```

After this change is applied,

- The cursor shape specified by the user for each mode is used.
- In insert mode, the `vim > cursor_shape > insert` setting takes
precedence over the primary `cursor_shape` setting.
- If `vim > cursor_shape > insert` is not set, the primary
`cursor_shape` will be used in insert mode.
- The cursor shape will remain unchanged before and after this update
when the user does not set the `vim > cursor_shape` setting.

Release Notes:

- N/A

Note:

This is implemented in a very hacky and one-off manner. The primary
change is to pass a rem size through the markdown render tree, and scale
all sizing (rems & pixels) based on the passed in rem size manually.
This required copying in the `CheckBox` component from `ui::CheckBox` to
make it use the manual rem scaling without modifying the `CheckBox`
implementation directly as it is used elsewhere.

A better solution is required, likely involving `window.with_rem_size`
and/or _actual_ `em` units that allow text-size-relative scaling.

Release Notes:

- Made it so Markdown preview uses the _buffer_ font size instead of the
_ui_ font size.

Closes #21684
Closes #28463
Closes #28264 

This PR fixes Zed hanging when scrolling over single line input fields
with `scroll_beyond_last_line` set to `vertical_scroll_margin`. The
change here is to fix the calculations of available lines.

The issue only arises with the setting present because with all
overscroll settings and `max_row` being 1 for single-line editors, the
calculation would still return the correct value of available lines,
which is 1. However, with overscrolling set to `vertical_scroll_margin`
and that set to any value greater than 0, the calculation would return
that the single-line editor has more than one line, which caused the
issues described above (Actually, setting `vertical_scroll_margin` to 1
works for some reason, overscrolls "properly" and does not cause a
crash. But I really did not want to investigate this buggy behavior
further).

This PR fixes this by always reporting the number of available lines as
the line number value for single line editors, which will (mostly) be 1
(for more context see the discussion in this PR).

Release Notes:

- Fixed an issue where Zed would crash when scrolling over single line
input fields and `scroll_beyond_last_line` set to
`vertical_scroll_margin`.

Various improvements to `zlog` including:

- Enable filtering by module (reproducing `env_logger` behavior) both
through env and settings.
- Note: filtering by module currently does not account for parent module
configuration, but does account for crate configuration.
i.e. `crate=trace` will enable `TRACE` messages in `crate::a` and
`crate::a::b` modules, but `crate::a=trace` will not enable trace
messages in module `crate::a::b`
- Implementing the `Log` trait for `zlog::Logger` to support gradual
transition and evaluate tradeoffs of always going through `log` crate.
- Added the ability to turn off logging for a specific filter (module or
scope) completely by setting it to `off` (in env: `crate::a=off`, in
settings: `"project.foo": "off"`)
- Made it so the `zlog::scoped!` macro can be used in constant
expressions, so scoped loggers can be declared as global constants

This PR adds functionality to right click in terminal create new
selection if none present. The selection is identical with double click
a text in terminal, plus the logic is moved from the double-click in the
terminal::mouse_down.

Closes #28787 

The context menu appears before the modal because it is a Deferred
element, which is always displayed above normal elements.

Release Notes:

Previously, the editor context menu appeared before the Command Palette.
This commit ensures the editor context menu is hidden when a modal,
including the Command Palette, is opened.

Just a quick quality of life improvement to make keyboard navigation in
this view a bit better. When you open the Component Preview view now,
the "filter" search input will be focused right off the bat.

This pull request will print all the used tools and their failure rates.
The objective goal should be to minimize that failure rate.

@tmickleydoyle: this also changes the telemetry event to report
`tool_metrics` as opposed to `tool_use_counts`. Ideally I'd love to be
able to plot failure rates by tool and hopefully see that percentage go
down. Can we do that with the data we're tracking with this pull
request?

- agent: Correct over-indentation in search/replace strings from model

This is also how VSCode tackles this issue. I think this should be

it can be addressed later.

This PR renames the `regex_search` tool to `grep` because I think it
conveys more meaning to the model, the idea of searching the filesystem
with a regular expression. It's also one word and the model seems to be
using it effectively after some additional prompt tuning.

It also takes an include pattern to filter on the specific files we try
to search. I'd like to encourage the model to scope its searches more
aggressively, as in my testing, I'm only seeing it filter on file
extension.

mistral site, but codestral-latest is newer and appears to be cheaper

* Adds a fast / cheaper model to providers and defaults thread
summarization to this model. Initial motivation for this was that
https://github.com/zed-industries/zed/pull/29099 would cause these
requests to fail when used with a thinking model. It doesn't seem
correct to use a thinking model for summarization.

* Skips system prompt, context, and thinking segments.

* If tool use is happening, allows 2 tool uses + one more agent response
before summarizing.

Downside of this is that there was potential for some prefix cache reuse
before, especially for title summarization (thread summarization omitted
tool results and so would not share a prefix for those). This seems fine
as these requests should typically be fairly small. Even for full thread
summarization, skipping all tool use / context should greatly reduce the
token use.

Release Notes:

- N/A

Previously, we were including the dummy text "Here are the tool
results." whenever reporting tool call results. I'm worried this is
adding noise and confusing the model, because the user didn't actually
say anything. This inserts an empty message to be populated later. My
preference would be something less stateful, where tool results (or
batches of them requested simultaneously) would be sent to the model as
soon as they were ready, without bothering to do this message
association dance. But for now, this seems to work.

Before, we used to debounce selection highlight because it needed to
search the whole file to show gutter line highlights, etc. This
experience felt extremely laggy.

This PR introduces a new approach where:
1. We query only visible rows without debounce. The search function
itself is async and runs in a background thread, so it's not blocking
anything. With no debounce and such a small search space, highlights
feel realtime.
2. In parallel, we also query the whole file (still debounced, like
before). Once this query resolves, it updates highlights across the
file, making scrollbar markers visible.

This hybrid way gives the feeling of realtime, while keeping the same
functionality.


https://github.com/user-attachments/assets/432b65f1-89d2-4658-ad5e-048921b06a23

P.S. I have removed the user setting for custom debounce delay, because
(one) now it doesn't really make sense to configure that, and (two) the
whole logic is based on the assumption that the fast query will resolve
before the debounced query. A static debounce time makes sure of that.
Configuring it might lead to cases where the fast query resolves after
the debounced query, and we end up only seeing visible viewport
highlights.

Release Notes:

- Improved selection highlight speed.
