This PR improves how we display markdown tables by relying on grids
rather than flexbox. Given this makes text inside each cell wrap, I
ended up removing the `table_overflow_x_scroll` method, as it was 1)
used only in the agent panel, and 2) arguably not the best approach as a
whole, because as soon as you need to scroll a table, you probably need
more elements to make it be really great.
One thing I'm slightly unsatisfied with, though, is the border
situation. I added a half pixel border to the cell so they all sum up to
1px, but there are cases where there's a tiny space between rows and I
don't quite know where that's coming from and how it happens. But I
think it's a reasonable improvement overall.

Release Notes:
- agent: Improved table rendering in the agent panel, ensuring cell text
wraps, not going off-screen.
Follow up #40736
Clean up `CodeBlockRenderer::Custom` related rendering per the previous
PR
[comment](https://github.com/zed-industries/zed/pull/40736#issuecomment-3503074893).
Additional note here:
1. The `Custom` variant in the enum `CodeBlockRenderer` will become not
useful since cleaning all code related to the custom rendering logic.
2. Need to further review the usage of code block `metadata` field in
`MarkdownTag::CodeBlock` enum.
I would like to have the team further review my note above so that we
can make sure it will be safe to clean it up and will not affect any
potential future features will be built on top of it. Thank you!

### 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#34224
### Release Notes:
- AI: Show horizontal scroll-bars in wide markdown elements
Also skips indexing files that don't have a suffix that indicates a
known language, and skips when the language doesn't have an outline
grammar.

### Background
On Windows, paths are normally separated by `\`, unlike mac and linux
where they are separated by `/`. When editing code in a project that
uses a different path style than your local system (e.g. remoting from
Windows to Linux, using WSL, and collaboration between windows and unix
users), the correct separator for a path may differ from the "native"
separator.
Previously, to work around this, Zed converted paths' separators in
numerous places. This was applied to both absolute and relative paths,
leading to incorrect conversions in some cases.
### Solution
Many code paths in Zed use paths that are *relative* to either a
worktree root or a git repository. This PR introduces a dedicated type
for these paths called `RelPath`, which stores the path in the same way
regardless of host platform, and offers `Path`-like manipulation APIs.
RelPath supports *displaying* the path using either separator, so that
we can display paths in a style that is determined at runtime based on
the current project.
The representation of absolute paths is left untouched, for now.
Absolute paths are different from relative paths because (except in
contexts where we know that the path refers to the local filesystem)
they should generally be treated as opaque strings. Currently we use a
mix of types for these paths (std::path::Path, String, SanitizedPath).

For read_file and edit_file, show the worktree-relative path if there's

This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.

Closes#32354
The issue is that we render selections over the text in the agent panel,
but under the text in editor, so themes that have no alpha for the
selection background color (defaults to 0xff) will just occlude the
selected region. Making the selection render under the text in markdown
would be a significant (and complicated) refactor, as selections can
cross element boundaries (i.e. spanning code block and a header after
the code block).
The solution is to add a new highlight to themes
`element_selection_background` that defaults to the local players
selection background with an alpha of 0.25 (roughly equal to 0x3D which
is the alpha we use for selection backgrounds in default themes) if the
alpha of the local players selection is 1.0. The idea here is to give
theme authors more control over how the selections look outside of
editor, as in the agent panel specifically, the background color is
different, so while an alpha of 0.25 looks acceptable, a different color
would likely be better.
CC: @iamnbutler. Would appreciate your thoughts on this.

Clearly, the selection in the after doesn't look _that_ great, but it is
better than the before, and this PR makes the color of the selection
configurable by the theme so that this theme author could make it a
lighter color for better contrast.

Follow-up to #24797
This PR ensures some cursor styles do not change for draggable elements
during dragging. The linked PR covered this on the higher level for
draggable divs. However, e.g. the pane divider inbetween two editors is
not a draggable div and thus still has the issue that the cursor style
changes during dragging. This PR fixes this issue by setting the hitbox
to `None` in cases where the element is currently being dragged, which
ensures the cursor style is applied to the cursor no matter what during
dragging.
Namely, this change fixes this for
- non-div pane dividers
- minimap slider and the
- editor scrollbars
and implements it for the UI scrollbars (Notably, UI scrollbars do
already have `cursor_default` on their parent container but would not
keep this during dragging. I opted out on removing this from the parent
containers until #30194 or a similar PR is merged).

Release Notes:

tl;dr: This adds `.block_mouse_except_scroll()` which should typically
be used instead of `.occlude()` for cases when the mouse shouldn't
interact with elements drawn below an element. The rationale for
treating scroll events differently:
* Mouse move / click / styles / tooltips are for elements the user is
interacting with directly.
* Mouse scroll events are about finding the current outer scroll
container.
Most use of `occlude` should probably be switched to this, but I figured
I'd derisk this change by minimizing behavior changes to just the 3 uses
of `block_mouse_except_scroll`.
GPUI changes:
* Added `InteractiveElement::block_mouse_except_scroll()`, and removes
`stop_mouse_events_except_scroll()`
* Added `Hitbox::should_handle_scroll()` to be used when handling scroll
wheel events.
* `Window::insert_hitbox` now takes `HitboxBehavior` instead of
`occlude: bool`.
- `false` for that bool is now `HitboxBehavior::Normal`.
- `true` for that bool is now `HitboxBehavior::BlockMouse`.
- The new mode is `HitboxBehavior::BlockMouseExceptScroll`.
* Removes `Default` impl for `HitboxId` since applications should not
manually create `HitboxId(0)`.
Release Notes:
- N/A
* stopped fetching LSP tasks for too long (but still use the hardcoded
value for the time being — the LSP tasks settings part is a simple bool
key and it's not very simple to fit in another value there)
* introduced `prefer_lsp` language task settings value, to control
whether in the gutter/modal/both/none LSP tasks are shown exclusively,
if possible
Release Notes:
- Added a way to prefer LSP tasks over Zed tasks
Previously, we forgot to associate the `Markdown` entity to
`MarkdownElement` during `prepaint`. This caused calls to
`Context<Markdown>::notify` to not invalidate the view cache, which
meant we would have to wait for some other invalidation before seeing
the results of that initial notify.
Release Notes:
- Improved responsiveness of mouse interactions with the agent panel.

Related to #31460 and #28635.
Release Notes:
- Fixed redraw delay of documentation from language server completions
and added caching to reduce flicker when using arrow keys to change
selection.
Closes#31460
While this is now much better than it was, the documentation still
flickers when changing selection. Hoping to fix that, but it will be a
much more involved change. So leaving release notes as "N/A" for now, in
anticipation of the full fix.

For some reason `pulldown_cmark` treats \````` as a codeblock, meaning
that we could end up with an invalid range generated from
`extract_code_block_content_range` (`3..2`)
Closes#30495
Release Notes:
- agent: Fix an edge case where the editor would crash when model
generated malformed markdown
Closes https://github.com/zed-industries/zed/issues/30411
Rendering as markdown gives us text selection and copying for free. In
the future, we may want to explore having these commands be actual
editors, allowing you to step in, change the command, and re-run it
right from there.
Release Notes:
- agent: Made the terminal command in the tool card selectable and
copyable.
After merging #30364 I realized why it was unnecessary to fix the code,
and was more efficient before. UTF-8 does not use the standard 0-127
ASCII range for multi-byte chars. So this reverts that change and
documents why the code is valid.
