Closes https://github.com/zed-industries/zed/issues/37743

Release Notes:

- Fixed agent panel panicking when streaming indented codeblocks from
agent output

This can lead to an infinite regress when using a language server that
supports pull diagnostics, since the excerpts for the diagnostics editor
are set based on the project's diagnostics.

Closes #36772

Release Notes:

- Fixed a bug that could cause duplicated diagnostics with some language
servers.

The audio crate will use the denoise crate to remove background noises
from microphone input.

We intent to contribute this to rodio. Before that can happen a PR needs

This PR updates the Cloud language model provider to use the `message`
field from the Cloud error response, if it is present.

Previously we would always show the entire JSON payload in the error
message, but with this change we can show just the user-facing `message`
the error response is in a shape that we recognize.

The problem from issue #37509 comes from local virtual environments
created with certain approaches (including the 'simple' way of `python
-m venv`) not having a `.project` file with the path to the project's
root directory. When the toolchains are sorted, a virtual environment in
the project is not treated as being for that project and therefore is
not prioritized.

With this change, if a toolchain does not have a `project` associated
with it, we check to see if it is a virtual environment, and if it is we
use its parent directory as the `project`. This will make it the top
priority (i.e. the default) if there are no other virtual environments
for a project, which is what should be expected.

Closes #37509

Release Notes:

- Improved python toolchain prioritization of local virtual
environments.

My pre push hooks keep failing on these. This is easier then disabling
and re-enabling those hooks all the time :)

Move keyboard shortcut for `pane:GoForward` so it's going to be
displayed as a shortcut hint in UI. Currently `Forward` is shown as a
hint, which isn't consistent with `GoBack` action and can be confusing.

Release Notes: 

- Improved the displayed keybinding for the `pane::GoForward` action on
Linux.

Release Notes:

- Fixed filled button hover background.

This appears to be a minor calculation error, not an intentional use of
this value.

If we pass `0.92` to `fade_out`, the calculated will be `alpha: 0.08`.

Release Notes:

- Added tooltip to Git branch picker items, making it easier to
distinguish long branch names.

Closes #37028

I noticed many projects use Tailwind in plain TypeScript (.ts) files, so
it makes sense to support them out of the box, alongside .js and .tsx
files we already handle. For example, see
[supabase](https://github.com/supabase/supabase/blob/master/packages/ui/src/lib/theme/defaultTheme.ts).

Note: You’ll still need to add `"classFunctions": ["cva", "cx"],`
manually for Tailwind completions to work in `cva` type methods. This is
because you don’t want completions on every string, only in specific
methods or regex matches. This is documented.

Release Notes:

- Added out-of-the-box support for Tailwind completions in `.ts` files.

Follow the macOS app style guideline.

## Summary
Adds a "Copy as Markdown" button to the documentation toolbar that
allows users to easily copy the raw markdown content of any
documentation page.

This feature is inspired by similar implementations on sites like
[Better Auth docs](https://www.better-auth.com/docs/installation) and
[Cloudflare Workers docs](https://developers.cloudflare.com/workers/)
which provide easy ways for users to copy documentation content.

## Features
- **Button placement**: Positioned between theme toggle and search icon
for optimal UX
- **Content fetching**: Retrieves raw markdown from GitHub's API for the
current page
- **Consistent styling**: Matches existing toolbar button patterns

## Test plan
- [x] Copy functionality works on all documentation pages
- [x] Toast notifications appear and disappear correctly
- [x] Button icon animations work properly (spinner → checkmark → copy)
- [x] Styling matches other toolbar buttons
- [x] Works in both light and dark themes

## Screenshots
The button appears as a copy icon between the theme and search buttons
in the left toolbar.

support for injecting sql, json, yaml, xml, html, css, js, lua and csv

if you use `/* lang */` before string literals, highlights them

```

Closes #ISSUE

Release Notes:

- (preview only) restored ctrl-shift-{left,right} for Larger/Smaller
syntax node. This is VSCode's default and avoids the breaking change
from #37874

Release Notes:

- When an agent requests a tool that doesn't exist, this is now treated
as a failed tool call instead of stopping the thread.

Do not report all open buffers to new instances of the same language
server, as they can respond with ~spurious errors.

This regressed in  https://github.com/zed-industries/zed/pull/34142

Closes https://github.com/zed-industries/zed/issues/35017

Release Notes:

- Fixed Zed overly notifying language servers about open buffers, which
could've resulted in confusing errors in multi-language projects (in
e.g. Go).

Improve the layout and styling of the tool list in the
AgentConfiguration, ensuring better responsiveness and visual clarity.

Closes https://github.com/zed-industries/zed/issues/35603

Release Notes:

- Fixed shell selection for terminal tool

This fixes terminal-based authentication for external ACP agents (Claude
Code, Gemini CLI) when file paths contain spaces, like "Application
Support" on macOS and "Program Files" on Windows.

When users click authentication buttons or type `/login`, they get
errors like `Cannot find module '/Users/username/Library/Application'`
because the path gets split at the space.

The fix removes redundant `shlex::try_quote` calls from
`spawn_external_agent_login`. These were causing double-quoting since
the terminal spawning code already handles proper shell escaping.

Added a test to verify paths with spaces aren't pre-quoted.

Release Notes:

- Fixed external agent authentication failures when file paths contain
spaces

Release Notes:

This PR lands some more improvements to the reworked scrollbars.

Namely, we will now explicitly paint a background in cases where a track
is requested for the specific scrollbar, which prevents a flicker, and
also reserve space only if space actually needs to be reserved. The
latter was a regression introduced by the recent changes.

The `Hsla` -> `Rgba` conversion sometimes results in negative (but very
close to 0) color components due to floating point imprecision, causing
the `.powf(constants.main_trc)` computations in the `srgb_to_y` function
to evaluate to `NaN`. This propagates to `apca_contrast` which then
makes `ensure_minimum_contrast` unconditionally return `black` for
certain background colors. This PR addresses this by clamping the rgba
components in `impl From<Hsla> for Rgba` to 0-1.

Release Notes:

- Fixed an issue where ANSI colors were incorrectly adjusted to improve
contrast on some background colors

This PR fixes the `BasedPyrightBanner`, making sure the banner is
completely hidden in the toolbar, when it was dismissed, or it's not
installed.

Without the fix, the banner still occupies some space in the toolbar,
making the UI looks inconsistent when editing a Python file. The bug is
**especially prominent** when the toolbar is hidden in the user's
settings (see below).

_Banner is shown_
