This PR adds a new component to the `language_models` crate called
`ConfiguredApiCard`:

We were previously recreating this component from scratch with regular
divs in all LLM providers render function, which was redundant as they
all essentially looked the same and didn't have any major variations
aside from labels. We can clean up a bunch of similar code with this
change, which is cool!

Release Notes:

This fixes the fact that the `AddSelectionToThread` action was visible
when `disable_ai` was true, as well as it improves its display by making
it either disabled or hidden when there are no selections in the editor.
I also ended up removing it from the app menu simply because making it
observe the `disable_ai` setting would be a bit more complex than I'd
like at the moment, so figured that, given I'm also now adding it to the
toolbar selection menu, we could do without it over there.

Release Notes:

- Fixed the `AddSelectionToThread` action showing up when `disable_ai`
is true
- Improved the `AddSelectionToThread` action display by only making it
available when there are selections in the editor

Adding a section clarifying the difference between regular threads vs.
text threads.

## Summary

Adds explanations for what each type of scrollbar indicator visually
represents in the editor.

## Description

This PR addresses the issue where users didn't understand what the
colored marks on the scrollbar mean. The existing documentation
explained how to toggle each type of mark on/off, but didn't explain
what they actually represent.

This adds a brief, clear explanation after each scrollbar indicator
setting describing what that indicator shows (e.g., "Git diff indicators
appear as colored marks showing lines that have been added, modified, or
deleted compared to the git HEAD").

## Fixes

Closes #31794

## Test Plan

- Documentation follows the existing style and format of
`docs/src/configuring-zed.md`
- Each explanation is concise and immediately follows the setting
description
- Language is clear and user-friendly

Since we removed the filtering step during context gathering, we want
the model to perform more targeted searches. This PR tweaks search tool
schema allowing the model to search within syntax nodes such as `impl`
blocks or methods.

This is what the query schema looks like now:

```rust
/// Search for relevant code by path, syntax hierarchy, and content.
#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
pub struct SearchToolQuery {
    /// 1. A glob pattern to match file paths in the codebase to search in.
    pub glob: String,
    /// 2. Regular expressions to match syntax nodes **by their first line** and hierarchy.
    ///
    /// Subsequent regexes match nodes within the full content of the nodes matched by the previous regexes.
    ///
    /// Example: Searching for a `User` class
    ///     ["class\s+User"]
    ///
    /// Example: Searching for a `get_full_name` method under a `User` class
    ///     ["class\s+User", "def\sget_full_name"]
    ///
    /// Skip this field to match on content alone.
    #[schemars(length(max = 3))]
    #[serde(default)]
    pub syntax_node: Vec<String>,
    /// 3. An optional regular expression to match the final content that should appear in the results.
    ///
    /// - Content will be matched within all lines of the matched syntax nodes.
    /// - If syntax node regexes are provided, this field can be skipped to include as much of the node itself as possible.
    /// - If no syntax node regexes are provided, the content will be matched within the entire file.
    pub content: Option<String>,
}
```

We'll need to keep refining this, but the core implementation is ready.

Second take on https://github.com/zed-industries/zed/pull/37765.

This PR adds support for styling elements (**b**, **strong**, **em**,
**i**, **ins**, **del**), but also allow you to show the styling text
inline with the current text.
This is done by appending all the up-following text into one text chunk
and merge the highlights from both of them into the already existing
chunk. If there does not exist a text chunk, we will create one and the
next iteration we will use that one to store all the information on.

Closes #40097

When multiple files are added sequentially to the agent panel, the
request JSON incorrectly includes "text" elements containing only
spaces. These empty elements cause the Zhipu AI API to return a "text
cannot be empty" error.
The fix filters out any "text" elements that are empty or contain only
whitespaces.

UI state when the error occurs:

### Summary

Restore the agent pane’s code-block horizontal scrollbar for easier
scrolling without trackpad and preserve individual scroll state across
multiple code blocks.

### Motivation

Addresses https://github.com/zed-industries/zed/issues/34224, where
agent responses with wide code snippets couldn’t be scrolled
horizontally in the panel. Previously there is no visual effect for
scrollbar to let the user move the code snippet and it was not obviously
to use trackpad or hold down `shift` while scrolling. This PR will
ensure the user being able to only use their mouse to drag the
horizontal scrollbar to show the complete line when the code overflow
the width of code block.

### Changes

- Support auto-hide horizontal scrollbar for rendering code block in
agent panel by adding scrollbar support in markdown.rs
- Add `code_block_scroll_handles` cache in
_crates/markdown/src/markdown.rs_ to give each code block a persistent
`ScrollHandle`.
- Wrap rendered code blocks with custom horizontal scrollbars that match
the vertical scrollbar styling and track hover visibility.
- Retain or clear scroll handles based on whether horizontal overflow is
enabled, preventing leaks when the markdown re-renders.

### How to Test

1. Open the agent panel, request code generation, and ensure wide
snippets show a horizontal scrollbar on hover.
3. Scroll horizontally, navigate away (e.g., change tabs or trigger a
re-render), and confirm the scroll position sticks when returning.
5. Toggle horizontal overflow styling off/on (if applicable) and verify
scrollbars appear or disappear appropriately.

### Screenshots / Demos (if UI change)

### Notes for Reviewers

- This is my first time contribution for `zed`, sorry for any code
patten inconsistency. So please let me know if you have any comments and
suggestions to make the code pattern consistent and easy to maintain.
- For now, the horizontal scrollbar is not configurable from the setting
and the style is fixed with the same design as the vertical one. I am
happy to readjust this setting to fit the needs.
- Please let me know if you think any behaviors or designs need to be
changed for the scrollbar.
- All changes live inside _crates/markdown/src/markdown.rs_; no API
surface changes.

Closes #40576
This PR makes Conda activation configurable and transparent by adding a
`terminal.detect_venv.on.conda_manager` setting (`"auto" | "conda" |
"mamba" | "micromamba"`, default `"auto"`), updating Python environment
activation to honor this preference (or the detected manager executable)
and fall back to `conda` when necessary.

The preference is passed via `ZED_CONDA_MANAGER` from the terminal
settings, and the activation command is built accordingly (with proper
quoting for paths). Changes span
`zed/crates/terminal/src/terminal_settings.rs` (new `CondaManager` and
setting), `zed/crates/project/src/terminals.rs` (inject env var),
`zed/crates/languages/src/python.rs` (activation logic), and
`zed/assets/settings/default.json` (document the setting). Default
behavior remains unchanged for most users while enabling explicit
selection of `mamba` or `micromamba`.

Release Notes:
- Added: terminal.detect_venv.on.conda_manager setting to choose the
Conda manager (auto, conda, mamba, micromamba). Default: auto.
- Changed: Python Conda environment activation now respects the
configured manager, otherwise uses the detected environment manager
executable, and falls back to conda.
- Reliability: Activation commands quote manager paths to handle spaces
across platforms.
- Compatibility: No breaking changes; non-Conda environments are
unaffected; remote terminals are supported.

Supersedes https://github.com/zed-industries/zed/pull/39910

At some point, these two (`index_for_x` and `closest_index_for_x`)
methods where separated out and some code paths used one, while other
code paths took the other. That said, their behavior is almost
identical:

- `index_for_x` computes the index behind the pixel offset, and returns
`None` if there's an overshoot
- `closest_index_for_x` computes the nearest index to the pixel offset,
taking into account whether the offset is over halfway through or not.
If there's an overshoot, it returns the length of the line.

Given these two behaviors, `closest_index_for_x` seems to be a more
useful API than `index_for_x`, and indeed the display map and other core
editor features use it extensively. So this PR is an experiment in
simply replacing one behavior with the other.
